This is how I want every thing to be explained. Great video
Thank you! We are working on that;)...
I am engaged in the pump cavitation simulation study, look forward to more exchanges
excellent!
me too !
Delusional science. Fails to explain the plasma spark. Does not detail the actual turbulance of the impellers. Does not mention the fact that the bubbles remain in gas for up to five atmospheres.. Does not explain the diamagnetic properties of the gas; a magnetized impeller would not pit. The obviously whack explanation of the bubble collapse. If the bubble is collapsing from a pressure increase externally driven, it would not collapse from one side.
It makes more sense to see that an increase in pressure is causing the bobbles to condense. The collapse happens from the central point of highest pressure. This causes a release of plasma energy delaying the collapse, shaping the torus, disrupting the sphere. The gas has been analyzed. It is made of clumps of water ions and radicals. The gas will dissasemble the atoms of the impellers. You will not find any flake in the fluid. Make a cavitator, collect the gas. It burns like natural gas whit more applications and no pollution.
Wonderful presentation. Whoever wrote-directed this video is a brilliant teacher. Thank you for you sharing your time!
I've been studying with youtube videos for years and I have never seen anything like this before! Superb explanation!
I am engaged in the pump cavitation simulation study, look forward to more exchanges .xzs528@163.com
Yes superb explanation!
I'm 45 years old, an engineer (computer systems) and I just now learned that pressure has an effect on the state of a liquid, I definitely was never into materials science or chemistry, but how did I miss this??? Simply put, this is the best learning video I have ever seen, on RUclips, VHS or any other medium, short, perfect illustrations, information reinforced several times, wow!!!!
It's common knowledge. How do you miss a thing like that?
Plus, you learned how to pronounce wapor.
A saying by physicists about engineers: "They're so narrow-minded that if you turn them sideways, their minds disappear." Yes, it's a bit arrogant.
Engineers might respond, "Physicists are jacks of all trades and masters of none." This is admittedly true, at least at the undergraduate level.
@@clarencegreen3071 You sound like me talking about biologists. Biology, the science that anyone can master if they can memorize things. It doesn't take actual intelligence just a good grasp of mnemonics. 😁😁
@@dumbotater2158lmao that had me fucked up for a minute. I was like wtf is she saying wtf is waper
I needed a video in order to remember all I have studied in my B.Sc. about cavitation, and this was amazing. Congratulations, and thank you all that have participated in the development of this video!
I've been supporting my engineering knowledge with a variety of educational RUclips channel since I started college and I have never seen such a extraordinary explanation of a engineering phenomenon. Impeccable!
This is the best video on the internet regarding the cavitation.
thank you - IET
This video is among the best that explain things with accurate language, great experimental results, vivid simulation and actual samples. Thanks!
This is without a doubt one of the best engineering and technology videos I have ever seen. Great job!
This video was exactly what I was looking for. Great explanation with real life examples. Thank you very much!
Simply the best cavitation animation. I have been working on this topic for a while and this video made me understood now very well. Thanks for the effort.
Perhaps the most intuitively explained video I ever watched!
This is the most through and fascinating video explanation I have ever seen on cavitation. Thank you for providing an easy to follow format.
The most detailed video on Cavitation I've seen till today, amazing job 🔥 🔥
Couldn't imagine this topic being explained any more clear. Thank you so much for this video
This might be the best Fluid Mechanics video on RUclips. Keep up the good work.
This is quite possibly the best explanation video on the internet.Well done
Subscribed! Amazing video! Very comprehensive and easy to understand! Keep up the good job!
I really hope you upload English versions of the other videos you uploaded in your E-learning in Thermodynamics and Fluid Dynamics playlists. Such amazingly crafted videos must be shared to the rest of the world! (plus I'm dying to see and learn from those videos myself!) More power to you!
BY FAR THE BEST VIDEO I HAVE EVER SEEN WHICH EXPLAINED CAVITATION IN MOST AWSOME WAY......THANX AND PLS KEEP UPLOADING SUCH EDUCATIONAL VIDEOS
Best video I've seen to explain cavitation, very detailed and clear
in 35 years of experience , i understood the cavitation visualy today
thanks for sharing the same.
The best Video I've watched explaining cavitation. Commendable.
New to the process control industry and this is a great video. Thank you so much for sharing this!
Absolutely incredible work. One of the best educational videos I've ever seen.
it was 7 years ago and I only watched it today and still amazed by it. I just know cavitation as bubbles formation. This is very helpful on my thesis for kaplan turbine. Thank you!.
*Drehbuch, Kamera, graphics, ton und Schnitt. Super hervorragend. Danke*
Omg, it cleared everything. I had so many doubts before watching this video.
You saved my time which I could waste by wandering on internet for answers.
Thanks to creators wherever you are whoever you are. 😇😇
Short & clear technical explanation. Thanks.
Best video ever about explaining cavitation!
wow really this is how our education system must be taking a topic and explaining from its fundamental origin to the practical problems
really appreciate it great work people responsible for the making of the video.
the best explanation of cavitation I ever heard! congrats
I have had some noise in my boiler for the past weeks,so i decided to look for a vídeo that explains something about it. Now i came across this video that explains how simple bubbles can destroy a whole system.what amazing video to watch,thanks.
Probably the best video in explaining cavitation..
Great Video!!!! I am Physcs teacher and my students have truly enjoyed it. Thanks
This is one of the best explanation videos I've ever watched. Thanks for making this
I can't believe it..! How can a video be this good? thank you so much for sharing
Absolutely incredible work. One of the best educational videos I've ever seen
same
Phenomenal video! Great job explaining with these awesome visualizations.
Better explanation than we had at trade school - thank you!
Well explained, with authentic proof and comprehensive way.. thanks..
I could watch this all day! Good job guys, and thank you very much.
This video is amazing! The way it's all explained makes it clear and easy to learn.
Wow!!!!! I've never seen any video with these many details. How can I not subscribe? Wonderful job. Thank you for sharing your wisdom.
Thank you very much for your subscription!
Can you thank me for my subscription too?
We're glad about every subscriber!
Even me?
One of the best cavitation videos!!
When pressure drops bubbles form when pressure gets back the same bubbles collapse. This collapse of buubles is accompanied by high velocity jets that cause erosion.
Correct. The low pressure in the bubble causes the high pressure water behind it to accelerate through it at high velocity, which cuts the bubble into a donut and gets shot out the other side at extreme speed.
Wayper pressure! Loved this vid....first time I have seen the bubble collapse in detail and the micro jet it emits....fascinating. Thank you😀 I realise the bubbles forming against a surface can only collapse from the exposed side, so the resulting micro jet must always be directed at that surface. Bubbles collapsing totally surrounded by fluid will jet in random directions.
wow this is very detailed. Professional AF, i couldn't understand everything but was helpful
Detailed explanation leaving no questions! Great job
I was revisiting cavitation as a result of high frequency sound waves in a laminar flow environment. This video rocks.
Excellent illustration.
A great video. Explained every tiny bit in a very straight forward manner.
Thank you for your feedback! We appreciate that!
Can’t be explained better than this ... just awesome
really thank you from all of my heart
this is the best explanation method ever
my graduation project defense still after 2 months and i have already known what to present
I was not directly searching for this but I am really glad I watched it! Great video!
IzakGt maybe you are also looking for a source that builds Cavitation Heaters?
Thank You so much, perfectly enlightened me this concept.
Im so impressed with this video. I was skeptical at first but DAMN. Thank you.
That is indeed easily explained! Thank you!
perfect! i have seen many videos of fluid but i hv never seen such kind of video. its perfect... thanks for the video
I'm studying by youtube from last 3 years ,
but this type of explained (very good than expectation ) video I never watched..
thanks to the team ..
this is an exceptionally well put together video....the animations and pictures, and explanations are awesome
Thanks. Very good video. You explain cavitation as easy as possible.
amazing explanation and visualisation of the cavitation phenomena. Thank you.
wow!! the kinda explanation I ALWAYS wanted to hear!!!
great video! explained the concept in such an awesome way that no text could do. thank you.
concept, explanation, graphics and examples. Thumbs up
Can't find such Such detailed explanation in my reference book!! Hats off
Really explained cavitation in a pretty simple way
All universities should adopt this type of video tutorials for their students.
Wonderful video and animation. The concept has been explained with great clarity. Thank you!
This is a great video. Thank you for sharing this knowledge.
I was just wanting a definition. I feel like a spent a week at MIT. Nice job
This video is gold.
This is great, helped me understand a big problem. Thanks!
Excellent video! Thank you.
This video explains really clearly about cavitation I have ever watched. When I was young I watched a video about cavitation bubble occur on blades of the submarine, the noise has exposed the submarine. However, I don't understand clearly until watching this video. Thank you very much.
I wished they explained things like this in Engineering school. The video is detailed and well done.
Great and clear video about cavitation.
Amazing video! Very well explained! Thank you👌
Great
Very clearly explained...your work is appreciated highly
Great video. Now I understand how cavitation occurs.
I love this video!! Wow what wonderful work!!
thanks...
such animations with diagramatic explanations led to easy understanding.
thank you for this wonderful explanation!
Excellent and clear. Super attention to images and video demonstrations and slow motion real camera work. So much better educationally than looking for long time at some face talking.
A couple of questions: Video says “evaporation” occurs only above 100 C at 1atmos, Maybe shouldn’t we call it “boiling” or “vaporization” to distinguish from evaporation? The latter term evaporation is generally used for what happens well below 100 when your wet clothes dry out for example.
Also just to let people know.. boiling needs “prompting” or seed points usually. It is so easy to superheat water in a kitchen microwave making a cup of coffee, throw in a spoon of coffee powder and see instant boil rather than instant coffee and often dangerously ejected. Reason for antibump granules in chemistry when heating liquids in test tubes.
Oh Gosh! So amazing this video. This is how every thing could to be well explained. wow, much better than Hollywood - Thank you so much!
Absolutely awesome explanation Loved it
Great explanation! Thank you so much.
I wish I could learn everything like this. Great video. Thanks a lot for sharing.
Beautifully explained!!
OMG this explanation is the best ive seen. Thank you :)
excellent explanation!!!! thank you for sharing
Wow!!!!! I've never seen any video with these many details thanks so much really ♥
Great visual explanation, thank you!
This is the only video was clarified my doubt thanks
Great video, the best on the topic imo.
Amazing animation.
Even though I knew that, I was mesmerized by the presentation and watched till the end.
the best way a topic can be explained.
Wonderfully presented! Great explanation!! 👏👏
This is one of the most amazing video for explanation iv'e ever watched. Damn nice
Best video on cavitation. A tought concept explained with utmost simplicity with animation. Can we just appreciate the real sounds of experimental cavitation bubble implosions attached to the animations? Superb work. Thank you.
agreed!
Amazing video . Thanks for sharing knowledge
