Corrections and FAQ in this comment! Official FAQ video will eventually be on the second channel youtube.com/@alphaphoenix2 1) Really cool demo of Kelvin-Helmholtz instability in a much more controlled situation: ruclips.net/video/qgamfo86FQo/видео.html
Thank you so much for making such amazing incredibly high-quality educational videos that are very entertaining. I always learn so much from your videos. THANK YOU!
Do you think this could be used as a random number generator ? something like Random red, green and blue value for back lighting, light intensity and slice on the whole tube, (well a picture of it) and calculate a number from pixel values ... ?
@@smartereveryday If you build it, Destin will come...and explain it in a thoroughly charming manner. Usually with highspeed cameras. Side note: Dude... Why are you up so freaking early?! 😵
No, no. It's hoarding, because it hurts less when you need the thing a few weeks after you finally threw it away after storing for years. That way it's unfortunate timing, rather than a failure of foresight and planning.
too right. one day i may need the adaptor to plug a phone i stopped owning 20 years ago into a device i have never owned, so i keep the thing. my wife keeps asking why i have the spare room full of old VCRs and CRT tvs. i say "they may be useful one day"
Have you tried running the water backward in the reverse osmosis tube? In water treatment plants, they do that to prevent clogging and preserve the throughput. They call this 'backwashing' or 'backflushing', but the don't deal with ink.
With RO you just remove the waste water restrictor and let it flush the surface of the membrane. There is a kit for that pump that would do it automatically for him but i don't thing it would work here because its a closed system.
came to second the back washing. RO shouldn't* need it but it would still totally work....do check the datasheet though. I havent worked in water filtration in years
A pressure triggered automatic backwash would be perfect. Adding a higher pressure shut off in case it eventually doesn't clear it might also be a good idea for the pumps health.
There are microfluidic devices called spiral separators. These are usually use separate different cells based on density. Probably not useful for sorting ink, but might be worth a try for fluorescent polystyrene particles?
17:55 The problem you had with the endcaps leaking might not actually be solved. Waterproofing 3d prints is notoriously hard because of the pores they have between the layers. This can be helped by extra perimeters and higher temperatures like you did, or smoothing the part by dissolving the surface with isopropyl alcohol vapors. However, most 3D printable plastics (like PLA and PETG which you used) are hydroscopic, which means that the plastic itself will absorb water. At very high pressure differences, like your 100 psi chamber, the water will still be forced through the plastic. A lot of submersibles with 3d printed parts have the same problem. You can try high-impact polystyrene (HIPS), which is not very hydroscopic.
I am a bad person - the word is hyGroscopic. ABS would work, and is extremely easy to vapour smooth using acetone. It is often used for pressurised water pipes.
The trick to printing a water tight end cap with petg is to use concentric solid infill with chamfers on the bottom. Because of the chamfers, each successive layer of concentric infill is offset from the one below it ensuring there's no straightforward path for the water through the print. You can also separate the print into an outer shell printed in vase mode for watertightness, and an internal part with the more complex geometry. I print canister filters for aquaculture this way. You can also thin pvc glue with acetone and use it as a water proof coating in a pinch.
There are multiple things to consider with hygroscopic materials, in particular "how much" water it can absorb, and "how hard" it absorb water. PETG for example does not absorb a lot of water (about 0.2% from what I've found) but it absorb it quickly, that's why a PETG spool is affected quicker with ambiant moisture than PLA. On the other hand PLA does not absorb water quickly but it can absorb a lot. And another thing, hygroscopic and water resistant are two different properties. Hygroscopic is about water absorption and water resistant is about degradation in water. PETG is water resistant (PET, PETE and PETG are used in plastic bottles) while PLA is not water resistant.
What you want is ultrasonic separation. This is used in grand scale industrial applications. Basically using standing waves to "catch" particles. But be warned, that's a rabbit hole on it's own.
@@Axodus nope you're not. Controlled sound waves are far from uncontrolled vibrations. Also it's meant as a separation method below the tube. Unfortunately I was unable to find a public video on how it works and I'm not allowed to share the footage I have since it's under NDA and I really don't want to sour the relations with them since they are a valuable supplier.
@@Axodus it's ultrasound nothing a average human should perceive. There are of course individuals able to notice it. And kids / young adults of course.
Cool project! I also liked the "supposedly working" quip: that's the hallmark of fascinating physics: you may end up in a phase when you do nothing other than sit mesmerized and stare at whatever you have built. The story here in Göttingen goes that Max von Laue sat for half an hour just staring right at an x-ray tube with a screen in front of it when first being shown his crystallographic patterns.
Pretty cool. BTW, gear pumps are quite quiet. Especially if driven by servo and magnetically coupled (bit overkill, but that was setup we used for pumping printer ink)
Maybe try removing the flow restriction after the ink at regular intervals to wash away the ink fouling from your filter. Backflowing some water through the filter may also help clear the fouling, though I'm not sure if your filter can handle that.
I am so ready for the reverse osmosis video. I fell down the rabbit hole when I put one in for my ice maker, but I'm sure you'll go much deeper with your video.
The patterns at the end of the pipe really remind me of surfaces of gas planets. I would be really cool to have the same thing as two spheres where the liquid moves between a inner spinning and an outer static sphere
Enjoyed learning about this project! In my automotive electrical class, my instructor compared voltage to pressure in a water hose. Lots of similarities between hydraulic and electronic circuits as well. Understanding one helps understand the other- you're not weird for thinking that way!
You had me at "better than a lava lamp" I love lava lamps. Edit: Even better idea: Use smoke and a laser array instead of water. Still fluid but you're using one fluid instead of two so you don't have to filter anything.
This is like the fractionated elutriation filtered, color coded particle size, patterned laminar flow layer disruption display, from my impossible to implement ideas notebook. I'd love to see this with rheoscopic fluid, maybe laser planes, and remote control disruptions for things like vortex shedding analysis, to visualize even more more complex currents.
To make the filters last longer instead of ink use a long polymer of plastic with dark colour. Think tiny micro plastic beads that will be as fine as ink but easily stopped through a filter/
A fluid will always have laminar flow when is being sucked. Versa, it will always exhibit turbulent flow when is being pushed ( under pressure ). These 2 behaviors are governed by the local dynamic impedance. When a fluid is sucked, the suction effect creates zones of under-pressure which allow the fluid to start organizing (moving) itself through the path of least resistance/impedance and such, given enough time creates laminar though the engine fluid can have a curl gradient.
RO systems are really sweet. I tame a boiler that used a monster RO system to supply water. What kills the membrane is not have a high enough reject water. You have to waste water that flushes the filtered particles off the filter or it will plug up.
reverse osmosis filters need regular flushing through the 'brine' or 'waste' outlet to keep the membrane from clogging, and extend its lifetime by at least double.
Really interesting description of the filter, makes sense though why they have to make it from those large monomers (personally it reminds me of the struggles of manufacturing smaller transistors, if a bit more crude). I am starting into my last quarter as a matsci undergrad, and I love your videos.
Forget the filter! Set up a complex centrifuge cascade to separate the ink and water by their mass difference alone. As a bonus you can enrich uranium too
Your way of mixing science and engineering is infectious. Wacky ideas and none of them boring. Many of them people can do at home if they really wanted to.
I'm already looking forward for the osmosis video! That's something I would love to understand better (I can currently understand what happens but not why it happens).
heck ya man you should upload a 10 hour version or something on the 2nd channel of just the thing mixing! would be very memorizing, i bet it would collect a shit ton of views over time.
I was thinking about how to remove the particulate from the water more efficiently. Some kind of prefilter would probably be very useful, maybe a cyclonic filter? Or perhaps with a different ink, you could use biphasic solvent separation?
A centrifuge comes to mind to solve the filter and pressure issues, though loading and unloading it is kind of a challenge to automate and keep reasonably isolated from the outside world.
You could try back-washing the ro cartridge (reverse flow) by injecting clean water in the outlet, capping the inlet, and wash particles out the reject line
Totally awesome, and agree - I could hypnotically watch this on an endless loop. It would be cool if you used tiny capillaries at both ends. Inject the ink in one small center-positioned capillary from the left, and water through the others (on the left), and draw the water+ink through capillaries then funnel on the right......
The best alternative to ink I can think of might be those PC water cooling fluids with glitter in them. They make really pretty patterns and the particle size is probably at least a little more workable.
Very nice work. Destin will love it. Have you tried turning the input manifold upside down, to get rid of the air bubbles? Currently your water inlet is the highest point, your geometry looks like it would push out any bubbles, when the outlet is the highest point. I'm looking forward to the next video!
Now make a filterless version with either a large enough separatory vessel to let gravity do the work constantly with a lower powered pump or perhaps run it on a timer after you determine how long the separation time is. Perhaps more dense inks improve the settling/separation time as well.
watching it makes me think of the universes life. Huge explosion at the start, chaos ensues but as the time goes on it because more uniform in to the vacuum at the end to restart it
Filter fouling is the technical term for buildup. It's been awhile since I've even thought about this but I think filtration systems are designed for an optimal fouling range such that your gunk buildup is doing part of the filtration. The initial filtration is worse but your filter has an increased operational period so you are replacing it less often.
Yay other a alphaphoenix vid! Thanks for making my day. Also yes prepared for the onslaught of RUclips copier vids and mass-produced knockoffs on Wish and alibaba
If the ink is heavier than the water you could try a centrifuge filter but you might need an extra water tank just to get enough flow to spin it properly, won't work without speed. I'm impressed that the RO filter actually took out the ink and didn't clog immediately
You should mount the ink pipe coaxially with the water inlet pipe... This would allow you to initially "protect" the ink stream; assuming initial velocities of ink and water are the same, it would be cool to see how long until the ink starts mixing. Then, move to swirling inputs (vortices) for water and ink, testing both same direction rotation and counter rotation.
Sounds like you need to high pass filter some of the audio, I'm getting a good bit of static on mobile and desktop for this video. Maybe a good spot for reference is 4:28. Great video though!
8:27 If you want a simple way to get how the water has changed, take a look at Posy's video "Motion Extraction" After that it would be a pretty simple formula for averaging the "laminer-ness" of a fluid motion
12:01 I know what an Angstrom is, we used it back then for light wavelengths. I prefer SI, either 0.1 nanometers, or 100 picometers. You are my kind of crazy, sir.
Your filter clogging problem is probably due to the shellac (or just small carbon molecules - 50nm is just the "average" size. You might do well to have multiple RO filter cartridges. Two cartridges means twice the surface area of filter media for the same amount of ink and pressure, easier to flush the ink off the membrane. You could also use a couple of filter sizes to filter out any small shellac/carbon molecules from the ink so you can be confident that the only molecules in the system are large enough to not clog the filter. You might also add a reservoir for the water and ink. That could give you more control over pressure and you could remix a portion of your clean water with your dirty water to dilute the ink before filtering it, making it even more easier (yes I said it) to flush off the membrane.
I remember hearing that graphene would make a good filter years ago when that nobel prize was awarded, but apparently the diameter of a hole inside graphene is 5 nanometers. One angstrom is 0.1 nanometers. Yea, that filter is absolutely insane. Also instead of getting the air out of the tube did you think to maybe submerge everything instead?
It wouldn't have any science lesson around filtration, but you could try mica powder instead of ink. It'll never fully diffuse so that you can continue to see the flow patterns by just pumping it through the circuit.
Since the ink particles are quite large, consider using skimmer (same ones used in marine/salt water fish tanks to scoop out organic matter). Ink will collect n seperate container and it should potentially be clean for re-injection
I appreciate that you take safety precautions. Too many people in this tinkerer corner of RUclips are cavalier about the risks inherent in their projects. It just makes me think of how hard it is to get my chemist coworkers to properly segregate incompatible wastes or even care slightly about safety in the lab.

Since the ink particles are quite large, consider using skimmer (same ones used in marine/salt water fish tanks to scoop out organic matter). Ink will collect n seperate container and it should potentially be clean for re-injection
If you could make a small scale continuous flow centrifuge you could possibly separate the ink without using filters at all.
Go into the rockies and stand in awe looking at a glacier river mixing with a normal rivier. One is transparent and one is mirky white.
yall really should sub to this man i know you all love it
I appreciate that you take safety precautions. Too many people in this tinkerer corner of RUclips are cavalier about the risks inherent in their projects. It just makes me think of how hard it is to get my chemist coworkers to properly segregate incompatible wastes or even care slightly about safety in the lab.
Please make a schauberger version with a spiraling vortex tube :)
Could this be done with a solution of liquid crystal display juice? 😮
Oh my god and then you run a varying voltage behind it 😮
@@AlphaPhoenixChannelThere's a way! I'm brainstorming over here, but also holding my breath.
