Since RUclips is about to delete annotations, figured I'd post them here for everyone to see. Enjoy the video!
1:59 Whoops, this is meant to be an increase in pressure, not a decrease in pressure, my bad. Click on the card for more detail on the adverse pressure gradient.
What about the different types and shapes of rear diffusers?
Can vortex generators be used without a wing to reduce drag?
On the rear roof of the car or even the decklid?
@@ChargedTTq Vortex Generators are meant to keep the air that passes through your car attached to the boundary layer. Without them, at certain high speeds your air starts to disperse at the top of the car right before the roof slopes down. In a way they can reduce drag, but not a whole lot cause you still need other parts to help reduce drag.
Can u explain how vortices are created by vortex generator
RUclips deleted my subscription for here too
Thanks for the lesson Ryan Gosling!
maddudenyc 🙌🙌
He looks like Daniel Radcliffe too!
maddudenyc You win! 🙌🏻 lol
I was thinking that the whole time
@@ThePivoteer101 he's a hybrid, shall we name him Ryan Radcliffe or Daniel Gosling?
as every genius engineer must, you draw terribly. awesome explanation
He was using his left hand at an awkward angle
As a fellow left hander, we draw shit on purpose. If all our powers were on display, you would burn us at the stake. 😜
My professor met those standards 😂
better to have the brains than drawing skills ask the docs ahahahahahahahahahah!!! you need a bucket to dribble all your shit in to
Some people are sometimes unreasonably difficult to please. You’re getting a Mercedes F1 engineer explain things to you FOR FREE and you still find things to complain about. Unbelievable
I really appreciate the credentials. It's nice to finally see someone on youtube who actually knows their $hit. +1
It was that the credibility was presented which was awesome
Amen.
Agreed
Simon WoodburyForget well he got scouted to work for mercedes in the aero division in formula 1 so i think he knows what he’s doing
@@dandingerat exactly, I really dont understand why people like this simon call him idiot
yeah it is not some aerospace level of explaination but 99,9% wouldnt get it really or wouldmt care enough to watch
My favorite part of the video was when you set everyone on fire by proving you have you paper in this field.
Greatest ooof moment of all time
I've used this video as a supplemental explanation for my students in aerospace physics. Great job!
mildly informative? bro free engineering classes 🙌 bless your soul haha. I was at ASU studying mechanical engineering joined, FSA too but couldn't wait to build my own stuff. Hence I'm attending a top notch fabricating school. your videos are immensely helpful. I hope to get my fabricating RUclips page going soon 👍 video editing in process.
Subbed. I'm expecting good things from you, Andre. ;)
you got that channel?! id sub
;)
Ryan Gosling is now giving us lessons about car aerodynamics... What a time to be alive...
When you brought up the example of what they thought when designing the EVO´s aerodynamics I understood exactly how it would play out. It basically helps the wing to do it´s job more properly to push down the rear end for down force.
I will add to what Kyle is saying here - I drive a first generation Dodge Stealth with the so called "banana" spoiler which is at the base of the rear window. I tuft tested it and wound up with swirling blah airflow over the top of it. The tufts went in circles. After I added the vortex generators, the airflow is now nice and straight, top and bottom.
Damn I hate the room where you are speaking... that sound tho...
Drl2t if you don't like room echo then speed up the video, it speeds up the reverb decay.. I thought it would be engineers watching these 🤦♂️
@@bungcheese5901 hopefully no audio engineers and sound designers are watching this. That being said the video is very informative but the echo takes away from the quality
Yes.
I made a helpful comment to him on how to correct this problem.
As he is a top notch petsonality, I'm certain he will be on it immediately.
Did he just predicted that Civic type R will have the vortex generator
Why would somebody say you don’t know what your talking about? I have an aeronautical science degree and I enjoyed the refresher. Thank you! Great video!
This was very good! You mentions a whole slew of vortex generator types, it would great to have a video going over all those types and show them and pros and cons, performance etc. thanks!
Yes im needing a specific type, but it's very experimental on my racing helmet. Let me know if you get a reply etc.
Old vids are still informative. Wish I was an aerospace engineer majoring in race car dynamics. I'm just a home hack with no money trying to build race cars in my spare time.
Good for you! At least you're doing something. Something that will go fast and make happy noises.
I'm just a home hack with no money taking youtube engineering classes because I can barely afford to maintain the nearly stock vehicles I have lol
@@BrokeWrench I've not modified a vehicle in 16 years. I buy cars that are specced well enough that I can just drive them with no maintenance. Lol. Funnel all my money into my track car.
Plus I have a deal with my wife that ant of my sideline projects go into my race fund. I buy rusty old trailers and fix them and sell for profit and part out cars I get for cheap
good video very informative, if i could make a suggestion it would to reduce the echo from the room when filming.
+Kc Ros Check my new vids, the problems have been solved! Thanks for watching!
Outstanding videos. I'm an aero mech engineer myself, and have a huge passion towards aerodynamics. These vids are like crack to me. Keep 'em coming!
aerodynamics tips for better fuel economy please. that would be a great topic that everyone could apply.
Ryan East anything that reduces drag?
@@WetOlde I too would like to know more about Vortex Generators for improve MPG on my daily driver.
Which one's work, and how do I acquire them.
Tommy T.
@@michelletessin6702 remove your rear wing, automatically improve your MPG!
@@lindltailor not in every case, in sedans rear wing can reduce drag
@@lindltailor dont have a rear wing on my ioniq
When I was a Truck Driver we put Vortex Generator on the aft edge of the cabs and Trailers and the difference that made to stabilizing the vehicles was very impressive, and the unexpected fuel saving was a surprise but very welcomed.
F**k the haters, keep the information flowing!!! (no pun intended)
This is the problem with people. Asking for his background or a source is not "hating" it's common sense.
the fact you said "(no pun intended)" suggests it was intended.
It was intended to not be intended. :D
I'm Currently studying to become a aviation maintenance engineer... i had a hard time understanding exactly how vortex generators suck high energy air into the boundary layer... You said the exact same thing my instructor said in his explanation, but just seeing you use a diagram while you explained gave me an epiphany... thank you
Trust me , i know what im talking about 😂 i love this guy already
Best aero explanation out there! I'm looking to implement this tech for wing sails, endplated, Sail GP style. They use a double slot wing with a essentially a huge adjustable flap at huge angles. Ive never seen vortex gens on them. As you say, every little helps!
Would love to see examples of the different types of vortex generators you mentioned in a future video. Thanks for these, nice work!
Love what you do, man.
As a supportive comment, I'd like to mention there is a science or two on being able to hold the attention of the viewer/listener.
I'm talking about audio quality.
The ghastly echo in your voice recording which you created by relying on the built in mic of your camera...several feet away, can be easily solved by clipping a small mic to your lapel. You could also use a boom mic just out of your shot, but since you move around a lot, you"d need an operator. In other words, to hold the attention of even seriously interested, technically minded viewers, you need a mic close to your mouth. This will help you present your world class information in a world class manner.
Once again, love the great contribution to racing education that you make.
This video was quite helpful to me! It made it a lot easier for me to understand what vortex generators do and how they improve the airflow. Looking at this from an aviation perspective (specifically improving the stall characteristics of wings) this was an incredibly helpful video explaining how that works. I was previously confused as to how disturbing the airflow over the wing could work to improve the stall characteristics, but now it all makes sense! Thank you very much for your highly informative video!
I really wish more people who think they are gear heads were informed like you are. I have watched videos of people going down the road with there coors beer in there buddys truck calling out every car with any aerodynamic mod on screaming that they are a racer. I would have not know what a Swan Neck Wing was if it was not for your video. You make perfect sense when you explain. keep up the good work
Sir, you just efficiently described the major parts of my aerodynamics course. Bravo
Left handed drawing is difficult. I'm left handed so don't sweat it. Clear concise explanation. I'm currently re-engineering my 2017 truck for better gas mileage through engine calibration and I now realize that aero needs to be part of the solution. Underbelly as well as the roof to the rear wing need smoothing in order to cut down the CD of the vehicle to make more progress. 20% savings isn't enough for me.
I have an interest in aerodynamics, esp. for cars, so these videos are very crucial. Thank you for making these.
You really do need A LOT more subscribers. So in-depth stuff compared to any car related videos on youtube.
Engineering Explained needs to collab with him
Great presentation. As an aviator instructor, it helped me to understand and provide an excellent example for explanation.
Pro tip for acoustics, grap some towels or blankets and place them on the floor or around you to dampen some of the eco.
Also, good video :)
Thanks, Will look to your trainings before the aero
stages on the Jag.🏁
Best to you Scott Whitmire
Would it be too much to ask for you to make a video going over the different types of vortex generators like you did on the diffusers?
love your work. im a new subscriber and absolutely love what you do.
you remind me of Engineering Explained, but you go more in depth in real world workings rather than just concepts.
0:40 ayy lil flex
You have no idea how much your video helps me with my term paper.
Thanks,
I see vortex generators on airplanes that need increased short take-off performance also. Thanks for the informative vid. Now i have a better understanding of how those devices work.
really good video. you did not have lots of materials in the video but still the explanations were very much clear enough.
Hi, I watched your entire video. I don't know anything about this science but found your explanation interesting. Good video.
There are many different kinds of vortex generators, such as simple plow, shielded plow, triangular plow, scoop, twist interchanger, ramp, tapered fin, dome, shielded sink, wedge, vane, wing, fences, leading edge fairing, dorsal fin, etc.
Wow this video is amazing. I'm writing a paper on Vortex generators for my minor project and this surely helps!!
Nice video, good explanation for low velocity air flow. High velocity appears to react very differently, flow separation always occurs.
I so love getting knowledge from someone who actually has some. Thanks for sharing.
0:22 and not to mention now, former Mercedes-AMG F1 aerodynamicist
Because people hate on your vid is because you are alot smarter than all the haters together.
Best one yet. Love the beginning, chopping up the haters :). Great stuff Kyle. Keep on sharing the knowledge please. Regards JW
Thanxx bro.. finallyyy got it. Have been trying to understand VG , after watching a lot of videos, yours made complete sense. Thanks
Thanks for the information Kyle. It led to me do a lot more research to understand how they work. I realized that a vortex generator is useless on my car and possibly counterproductive.
Kyle, very well explained. Could you perhaps make a video to explain this concept on another application, be the edge of a bicycle tire. Mavic came out with the CXR and CX01 blade that smoothens the surface area where the tire mounts the rim, yet insisted on using their tire which has tiny ridges to create a gradient vortex at the leading frontal edge of the tire. In trying to understand their design and science I came accros this video. I would be curious to better understand where tp make this vortex on the edgw to have the greatest effect
Took me a while to find you. Like your videos. iRacer here PCA coach, so working with aero is new to me. Running a Merc AMG GT3 car. Thank you- it has got me thinking. --S
Nice you put in the remark about , keeping the marketing department happy 'cos so many things in a mass manufactured item comes down to the engineers being hijacked to keep the business model happy .
Thank you so much, that helped me a lot. I'll be having my exams on this coming week. I'm an aircraft maintenance engineer.
Excellent, Kyle!
I appreciate your diligence and hard work bringing aerospace to the masses
I had no idea there was such a thing. I learned something completely new and your explanation was clear and concise. Subscribed!
this comment is before I watch the video.
so, I think I understand what they are and what they do. they are a device which create vortecees which energizes the flow and forces it to more closely follow a surface without detatching and creating a wake.
let's see after the video if I was right, wrong or somewhere in between
Edit: I think I was right, I just didn't have the full knowledge behind it.
good video even tho it is old and the audio is pretty bad
Great videos - Would love something that goes a bit more in depth on what types of vortex generators the average person might DIY in their garage for a budget limited race car.
Lol love how you flexed your knowledge on us in the beginning of the video 😂
This is a trip back for someone who just started watching your stuff recently. (I like the beard, fyi)
Engineering Explained is a discount this guy.
xXxMartin96xXx make EE and this guy work on an f1 car
EE is mech engineer. It's a different story. He makes his job really well.
MUCH BETTER!
Frankly after watching your '30 second' explanation i couldn't stop scratching my head and thinking WTF?
I understand now :)
This has helped me alot in regards to understanding this phenomoinon.
the best explanation with examples thus far.
That was explained exceptionally well. Thank you!
Most enlightening, great stuff ... I like seeing cars with VGs and no spoiler. Hehehe ...
Never knew Ryan Gosling is a aerodynamic expert. Great video btw!
I 'd love a tutorial on airflow of engine ports on heads, both intake as well as exhaust. you certainly know your stuff!
there's a reason why the art of port flowing is called "the black art", there are many more variables affecting the gas flow, even good CFD software can struggle to accurately depict what happens in a port, head, and combustion chamber...
Lool that flex in the intro 💪🏾 tells me i came to the right channel 👍🏽
Ryan Gosling makes a really good point here. I'm going to install some vortex generators on my wagon , I've been hitting some very high speeds lately ,. my grandmother died in a very horrible way after being run over by a wagon, I think this could have been avoided if the wagon had vortex generators installed .
Cheers mate, Very helpful and good and the Explanation along with applying the Scientific Proof of what Vortex Generaters do. 💯
Kyle really out here proving his credentials serving up blade runner looks we don't deserve him
As someone studying aviation this was rather trippy looking at upside down wings heh
Great vid
Nice work man! U alongside with Engineering Explained make a perfect duo for enlightening us and making our automotive knowledge expand to respectable degree. Thanks
If you want to visualize the concepts turn on the pool filter in an in ground pool after dark, lights off, flashlight in hand, look at the shadows the water vortices make, note the compound impact the direction if flow as it navigates the low to high shape of grade of the pool, point the nozzles in various directions watch how the swirls react
That was absolutely brilliant... Spot on =)
Very helpful video. I am interested in the aeronautical application for VGs and your video explained it nicely. Be it a car or airplane wing the same principal applies, just you car guys want the lift downwards and we airplane guys want it the other way.
Thanks for a neat video.
Thanks for the brilliant set of videos realted to aerodynamics....YOUR CHANNEL IS SUBSCRIBED........PERIOD.....
Love the content. I used to have a Very-EZ airplane that had a canard wing.
This was very helpful and informative! Thank you for taking the time to explain them!!
It's been so many years but somehow I remember it was this video that had the exact moment I was looking for 0:22
Fantastic. I had never heard of vortex generators.
Man I wish I had known about this channel when I was taking fluid dynamics
Thanks for the great lesson.. i just can recommend you to put some echo and reverb dampening material into the room to improve acoustics.
Kyle, Great tutorial video's please don't take the negative comments seriously. 99% of the negative commenters have no education, very low income and are unhappy people.
please keep it up! Thanks
New subscriber, love this. Informative, interesting and best of all. It's understandable.
I will never look on a race car the same again.
Can you do a video on vortex generator profiles and what different profiles can be used for? Awesome channel btw. Really good info.
Well done. Was reading an article in the LA Times about Jet Blue retrofitting its A320's with vortex generators to reduce noise as the planes descend into the Long Beach airport. Begged the question "what is a vortex generator?" Your video provided the answer. But does beg another question..."are there any potential adverse outcomes to installing vortex generators on aircraft wings"?
I certainly trust you after that introduction buddy.
I feel informed and a bit educated, thank you sir
"this video is really boring"
Vtec at 04:57
*SNEEZES* i cant concentrate because its too funny to learn
Great vid- thank you. There are always crazy haters whose sole joy is to ruin someone else's day- please ignore them and continue your important work.
not sure why, but now I'm curious on the aerodynamic effects of the louvered back window covers you'd see on Camaros, RX7s, other hatches in the 80s, 90s.
you seem like the best person to give an honest evaluation; doubt you'll see a comment on a decade old video! lol
Love the trenchcoat, good info too. Thanks.
On your wing, on airplane wings, and on the F1 car photos at 7:09 in your video the vanes are fairly far ahead of the region that creates the adverse pressure gradient (APG). On your wing and on airplane wings the vanes are near the front edge of the wing. I assume that is to give enough room for the boundary layer mixing to occur before the air gets to the APG. On the Mitsubishi and on most cars with aftermarket vortex generators, they tend to put them immediately in front of the area of where the body suddenly slopes down creating an APG. I've always wondered how effective they could be when placed so far back. Thoughts?
You got a subscriber and a like from me. Thank you and please keep it up, this has been informative and it made complete sense. The reason I watched the video is because I am trying to improve my car for autocross and I wanted to learn about vortex generators. This was exactly what I needed. The only question I have left to answer is do they make more of an impact at higher speeds, my inclination is to say yes as it is probably easier to measure the impact they make at higher speeds vs lower speeds, but the effect they have is present regardless of speed, therefore I think it is wise to install these if your goal is to improve track times. Also I like the bit where you explain the "flaw" behind the evo designed vortex generators, as they are not the most efficient vortex generators, so I should do some research and find vortex generators that actually work before making a purchase. If you have a recommendation on a manufacturer of aftermarket vortex generators that would be superb (or you could always make them yourself, as I am sure you could make a competing product. Also wouldn't you think it help improve track times if vortex generators were installed at every angle?).
In simple terms; vortex gens are to suck the pressure aka reducing the high flow pressure and lower it to closer to boundary layer level. So it is a controlled mixing device.
Great video! Now I have a challenge for you, what would you do to make a 2015 beetle reach its maximum aerodynamic efficiency? The car certainly has an interesting profile
Great! Can you do one on fastbacks next? Maybe explain those fins on some of them?
thank you very very much for your time and your explanation
