Nikola Tesla had invented a very interesting one-way value. Let's understand the complete physics of this valve in this video.

I have never seen an actual working pulsejet engine using the Tesla valve. The reason for this is that the valve is too "soft" and absorbs a lot of gas before it is "full" and the choking effect becomes pronounced enough to cause compression in the combustion chamber. For that reason, any engine built with such a valve would be unlikely to run well -- if at all.
@notahotshot Keep telling yourself that, I guess.
This is omitting the electrical applications the design is really intended for.
The interesting thing about this apparatus is that the reduced flow from the output side is fairly consistent no matter how much pressure is on the input side. It's not adjustable but this would have applications where someone would need a relatively stable volume of liquid flow regardless of the changing input pressure. I think that is the real purpose of this valve, not so much being a one way valve.
@carls1959 of course it is, however not executable in industrial areas. Also it keeps getting larger the more u ads.
Ya but it seems like its a job that a conventional valve is still capable of. The only real benefit at the end of the day is reduced wear while having a lot more drawbacks than value
"The Tesla Valve cannot block the flow completely"
In other words, it is NOT a one way valve, but instead, is a flow restricter.
Add more units till it stops flowing...
@Mad Controller X It will still flow some, no matter how many units.
Like most things Tesla "invented" it works poorly.
that sounds like a Run DMC bar
A polarized flow restricter
Fluid dynamics is a very interesting and very complex field and has an impact on so many day to day things that we take for granted. Tesla was a true engineering genius.
hmmm
Like the valves and vessels of our blood.
I've never been more confused in my entire life watching this video. Nikola must've been a really smart guy, I give him a round of applause for being a smart guy
It isn't that confusing. In simplest terms, water goes in one direction meets barely any resistance any that it does it fixes when it meets back up. When it goes from the other direction the resistence it meets is amplified even more when it meets up due to how the water is being bent against itself. Now you take that and multiply it in on it self. With the resistant end you are basically multiplying like this 2x2x2x and so on and with the end that has no resistance you are multiplying resistance basically by 0 or close to it due to the forces that meet up agreeing with one another. Thus one end gives you a dribble due to the resistance being multiplied end over end and on the other you get a decent flow due to little to no resistance. At least that is what I grasp from it. Simple design with large consequences.
@Grim reaper You didn't grasp anything, sorry. It's orifice, nothing more.
In simple terms water will use all available space and you design the tube so that some of the water is forced through shapes designed to move it efficiently back towards the direction it initially came from.
@Shanopla Even simpler. One way water gets in its own damn way, the other way it don't. Thus flow is restricted in one direction but not in the other.
@Grim reaper hmm “own way” or the way we gave it by design? I would say each stream is going where we told it to!
Never thought Nicola Tesla would have had anything to do with fluid mechanics
Tienes razon. Es solo un video falso para que des like
@srtghfnbfg isn’t that what diodes do? There are plenty of electronics that keep electric field from saturating other components and keeps the current flowing in the right path.
amazing i like this
Tesla did a lot of work with fluid mechanics. Just check out the tesla turbine.
Edison : * this is my new invention *
The DeltaP seems depending on the flow rate. This will work great for mixing applications not sure about replacing check valve applications.
Great mind.! Great animation. Thanks.
Makes you wonder if they had Tesla's works in mind when designing tire treads that push rain out from under the contact patch. Cuz I'm looking at the first set uof examples up to the 3 minute mark and can't help but see tire technology as well.
Tesla was a genius that wasn't appreciated in his time. Definately can't use this as a check valve.
Something not mentioned in this video is that alongside the mentioned flow restrictions of the Tesla valve, after the first switchback the "main" flow will be directed towards the next switchback each time. It doesn't appear to be an even split into primary and secondary.
"Tesla's valve is dangerous, immoral, illegal and nefarious!"
---- Thomas Edison
Tesla and Edison met in London the affair was a short 6 months. The rivalry was mostly hurt feelings that neither could get past.
Remember “none of us are as smart as all of us” imagine if these two would have came together and joined forces!!
In essence it is a very simple idea. Break the flow into 2 pipes, one straight, and bend the other one to go into the opposite direction, when reunited. The reverse flow mostly ignores the second pipe because of its perpendicular-opposite direction. I don't think that Teslas design would work as a flood barrier though, with a road put in the middle. It probably works just when the pressure/size is big enough.
I think this also can be used for river to reduce floods!
Simple structure is tough against break and cheaper.
But I didn’t know Tesla has developed in dynamics field not in electric engineering.
In airflow through a duct in HVAC applications, turbulence causes restriction to flow. Turning vanes and proper transition design is vastly important, especially when the pressure available to move the air is so small. A small restriction doesn't cause a small difference in air distribution to an outlet, a small restriction means almost all the air goes to the least restrictive path. Poor duct design or installation can make air balancing almost impossible.
I noticed that secondary routes in the valve were always smaller than the target main.
When you say "let's see it work" pretty sure everyone was expecting a real life version. You can make anything happen with computer animation
Unless the animation is based on a correct simulation of the natural process then yes it's worthless.
I think anyone who knows basic physics will understand why this works
Indeed, repeating the animations that were used throughout the video and putting a "pump and pool" on the side of said animation isn't anywhere close to "let's see it work." Might as well cut out that section of the video, it adds nothing and is disingenuous.
@Nigs Whittington It's not really the same process though, these valves are more so based around fluid mechanics, suppressors are more about reverberating the sound waves in compartments that are the same both ways.
I wasted 5:20 of my life for him to say the "Tesla valve doesn't stop the water completely"
Dissolved solid buildup within a short time would render the valve useless. Mechanical valves can suffer the same, but the movement is often enough to restrict mineral buildup. I can only assume the same for unburnt fuel and carbon doposits in the pulsejet in the high turbulence areas leading to valve failure.
This is quality reminding me of old educational videos. Simply superb!
As a 20 year master plumber I love the design due to it not having any mechanical parts that could fail for a pressure reducing valve this would be great
this is very interesting, also amazing how physics works
Muchas gracias por su gran trabajo.... muy bien explicado. 👍
"One of the best things about dude is that he never takes credit for himself when he achieves something. He always respect us, the audience, and his team, and he is always polite in all of his videos. We congratulate ourselves on this achievement. More to come and everything to come''''❤❤😍😍...""...
The last diagram looks similar to water drip emitters used in irrigation , the flow is relatively the same under several different pressures . I made the EDM dies for Olsen Irrigations drip emitters which is how I know the internal design .
would have nice to see how it behaves in a situation where the flow reverses periodically
I was in the middle of nowhere and ended up here. Hence I watch this glorious video till end
@Whit h a
tbh same
@FarzBZ 987 d
@spontanious d
Same !
And that's two dimensional.
You could alternate units in the third dimension as well, or increase the number and density by adding successive units at small angular changes with many alternating pairs.
Then spiral the design to elongate the valve length.
Truly an under appreciated genius mind of science was Mr.Tesla. There’s been none like him since.
Except the guys that invented the transistor, the laser, the microchip, split the atom....
Since you did this video on fluid dynamics, how about a video on how a sound suppressor works?
I was wondering for what he designed this when watching this video, at the end, I noticed how brilliant the design was
I like that one can specifically use the small throughput to one's advantage
I always think that whoever invented tesla coils is a genius
The venous system works similarly. The valves stop backflow, while forming a bucket structure that causes the blood to turn back in the direction of the heart. Please do a video on Viktor Schauberger, the Austrian forest warden who used vortices to enhance fluid flow efficiency instead of considering them a nuisance.
hmmmmm
Wonderful learning from the genius that was Tesla.
I'm guessing the main reason this type valve hasn't caught on is simply because, as stated, it can not complete block the reverse flow.
For instance water without a lot of pressure behind it (from static height or a pump) will create less vortices and therefor less resistance.
The harder you push the water through (use a big pump), the pressure loss will increase exponentially, and so in relative terms it will be more efficient. It still won't stop flow completely though. It will also mean more damage to the valve due to pit corrosion (the same you get on ships propellers), and that would severely restrict the lifespan.
But it is certainly an ingenious design, no doubt.
Well the pulsejet concept at the end is a great example, also in theory could be used to replace reed valves in 2-stroke motors. The current carburetor system has some pressure loss anyways, a design like this could emulate the function of a reed valve without the problems of wearing out. And in the example of pulsejets, the pressures experienced in the combustion chamber are quite high indeed as well as being fairly frequent, which wears out traditional reed valves pretty quickly. It could also have applications in hydraulic logic, as a resistor as one user mentioned or as a flow regulating valve to enforce unidirectional flow.
بامم من. تنهي عع
It is indeed used in microfluidic systems, but there it has another purpose and that is mixing. The microfluidic channels have highly laminar flow so mixing becomes an issue. The Tesla valves are one of the most effective ways to mix your fluids.
Yeah poop would definitely stick everywhere 🙄
Acredito eu que ele simplesmente observou e estudou a anatomia das veias do corpo humano. É o mesmo princípio!
When I was a kid I read without prompting books that to this day I enjoy. Nikola Tesla was one of them. Interesting indeed
He had great understanding on the nature of water and how to apply it to motion
Tesla truly was a genius that we are still only now coming to realise…
Very cool! Thanks for sharing and great animation too
VERY DISAPPOINTING PRESENTATION, this "Learn Engineering" guy. I watched the alternative video and didn't see or identify anything in the "demonstration". The guy tried to only "suggest" that flow was "noticeably faster and slower". This is nothing more than an observation based on what he was "HEARING". There was absolutely NOTHING measured, either flow or pressure. So what if one direction creates more noise than the other direction? ------ Well I suppose the guy has some PhD degree (or just threw on a jacket and tie) and assumes people are supposed to accept the presentation as fact. Clearly, he doesn't know how to provide a presentation that is supported with factual monitoring equipment .....BUT HE THANKS YOU FOR THE LOVE.
Yes i see your animated videos.. It is very intresting and i understood everything
Yeah really good! I wait for more slow motion!
Well, intuitively I thought the flow going left to right was less restrictive but after the explanation I see the point. I propose a high pressure gas being allowed to expand from a small confined space to a larger area, and, if done in such a way as to not induce turbulent flow, will, due to conservation of energy, cause pressure to decrease, velocity to increase, and temperature along the stream to decrease. I will call my invention...air conditioning.
I mean, while he did patent it, I feel like since it's used in so many applications its less of a product and more of an invention, but I digress. Interesting video!
Very cool in its simplicity. It makes me think that such a valve could be applied to mechanical combustion engines as far as two strokes, replacing, or modifying, the reed valve. Food for thought. (has it been done?)
hmmm

I'd imagine putting the Tesla valve on an angle could eliminate flow completely.
Also the primary flow in tesla valve isn’t a straight line. For every section of the “bucket” structure the primary path is tilted so that it matches the entrance of the next bucket structure, so making is very effective at dividing the primary flow into a secondary flow that opposes itself
Очень интересно, спасибо!
Благодарю, получил удовольствие от просмотра. 🤗 👍 🇷🇺
This is very interesting. I wonder if this is applicable in fuel injection systems for cars. Perhaps to produce a more lean air to fuel mix therefore possibly making gasoline engines more efficient.🤔
its a restriction orrifice.... so nope
this wont stop water from flowing backwards. it will drastically reduce the flow but inevitably a dribble will be allowed when flowing in reverse, it has limited applications but the applications it does have are critical.
Interesting design, considering when it was made. I'm definitely awed.
Well I'm suprised the video does not show an actual water test.
@insert good name Yes I know its a toy, but it's interesting!
@insert good name , valve expert?
@InThe MaZe Don't know, but I'm seemingly a common sense "expert".
@insert good name https://youtu.be/sxvIQMnKhIg
This video will help a bit. Many more like this. It really is a valve, just no moving parts as I have stated numerous times above. I've worked with many valves, motors, hoses, connections for many years as im a hydraulic and pneumatics engineer for a earth drilling manufacturer. If I don't approve it, it doesn't go on the machine. Got it, ive done every bill of material, on each standard unit, which includes, triplex mud pumps, water cleaning systems, and drilling units. When it comes to custom designs, im the one on the clock.
Because it doesn't work, it like perpetuum mobile. Simple physics.

https://www.youtube.com/watch?v=ozFBsMyyDSE - Here is a simple experimental demonstration of the Tesla valve. Some people have casted doubt about its effectiveness. Trying to understand the Tesla valve and Nikola Tesla's mind was a real fun. Thank you for the love :)
