Tesla invented the Tenga. Don't @ me

The Tesla Valve Tesla’s valvular conduit is mostly misunderstood as presented in much of literature and most media such as RUclips in recent years. This device cannot be called a valve if used as an inline flow resistor. It is usually but erroneously demonstrated as a ‘one way valve’ with fluid, be it gas or liquid where the pressure drop is considerably larger in one direction flow than in the opposite. To use electrical analogy, this is not a diode but a resistor, therefore, the word valve is inappropriate. The expected ‘valve’ action (check or non-return valve) is unimpressive if anything. Tesla originally construed his ‘valvular conduit for gas flow, and in fact specifically for gas under pulsating pressure. In this application, it may be called a ‘valve’ or a ‘fluid diode’. Gas under hight frequency pulsating pressure takes advantage of this clever topology and is free to flow in one direction with relatively negligible losses and practically no backflow. With careful design, Tesla’s valvular conduit is a true pulsating gas diode with no moving parts. An illustrative application would be an IC engine exhaust manifold. It should also be noted that this valve will have optimal performance at a single design point, i.e., temperature, fluid type, volumetric flow and frequency, so that any change of a parameter will have it operating off optimum. As for making a modern design, I imagine a cut and try method with FEA would be used.

If someone were do make a path with the Tesla valve's path, I'm sure people will get lost going the wrong way.

I'm wondering if they couldn't do this with the Mississippi River to get rid of locks. The valves would be aimed to resist southward flow of water. The river could still flow south, but slowly, so water would 'pile up' and make the locks unnecessary. The design still allows a central channel that is straight. The only thing is it might be too hard to steer a ship with all the side currents buffeting it side to side.

😂 now try it with 1mm valve and gas fuid

Sir. You ARE a very smart man. Please do not stop your pursuits.

Pretty smart and it would allow fish relatively safe passage both up and downstream. With small vortices and areas of slow waterflow it emulates a natural river environment.

Thanks for not putting 10 minutes of video explaining the valve and just cutting to chase instead.

interesting work indeed. I want to use a tesla valve for classification. So for seperation tech, i.e. I want to remove suspended solids from a stream of liquid water but I want to compare the performance of the tesla valve to a cyclone in the seperation by size and density. I know this can be done but I just don't know by what specifications. I think there should be some special type of "tesla valve" that will behave different from the generic tesla valve. I already have about 7 different classifications for this type of valve.

Reminds me of the LA Traffic System

Who's coming from RCE ?

This was a nice model but it needs to be sealed since pressure is required and not simple low velocity flow. The resistance efficiency of the valve increases with the pressure and velocity of the medium used. There is also a time factor between flow direction changes for it to operate in a practical way. But a very interesting idea for safe aquatic life to move through. Having raised fish in a multi tank arrangement, you'd be surprised how they navigate against the flow when they have the chance. I kept having to take fish out of the common filter that service 5 tanks as the smaller fish swam right through the circulating tubing, against the flow. I used a very low pressure between the tanks so as to keep their environment as unmolested as possible. I eventually had to use screens to prevent their movement through the system as larger fish were feeding on smaller ones as they came through the outlets. The larger fish sat by those openings for weeks afterwards waiting for the smaller food size fish to come through after I added the filters. It was a little amusing to watch.

まあまあ流れてますね、やっぱり空論なのか。

show us the reverse

Work better for gases

A Tesla valve isn't meant to be so huge and not for fluid but gas.

Lots of armchair scientists in this comment section…

Very good

El experimento mejor hecho que he visto de la válvula de Tesla por ahora.

Works great, the dye easily flowed through the restrictions

This is a very interesting alternative to the various engineered channels that are currently used to help fish negotiate their way upstream to a higher water level by swimming against the general water flow diection in such channels. It works by providing zones of low speed water where the fish can rest before making short spurts through zones of faster water to higher resting zones - eventualy getting to the final upstream water level before becoming so fatigued that they are washed back down the channel. The beauty of this approach is that the zones of low water speed are created by the 'Tesla Valve' geometry rather than by solid barriers (waffles, chevrons etc in other designs) within the channel - so less prone to gravel etc building up within the channel. At very high flows, the Tesla valve would be submerged under a region of fast moving water - but there will still be zones of lower speed water within the valve that the fish would detect and make use of. I am ashamed to say that I would have been tempted to run a test with some real fish to see how they would respond to the flow in the channel - not a very ethical approach as the water in the test channel is pumped and recirculated ......... the fish would probably not survive that experience. The link provided below the video leads to the thesis document (in English) which explains the testing that was undertaken in much more detail. At the end of the thesis it mentions that the test channel is in storage but is still available ........... now where as those goldfish I won the fair?

Что это?

what's the terrible camer work!

I don't think anyone on these comments even know what this guy objective is.

I'd like to see the speed or pressure drop when it runs in the reverse direction.

ある程度は、止められるけど 微妙な感じ。

うまくいってる？ 微妙な感じがします。

Ur valve is open, original was sealed on top.

Very cool stuff

Como engenheiro elétrico, Nikola Tesla inventou está válvula para usar com fluidos, mas ao lê sua patente podemos perceber que está válvula é um dispositivo elétrico é uma peça para ser usada como parte de outro dispositivo, seu funcionamento asemelha se a um diodo onde a corrente elétrica passa por um lado e não volta, fiz a tradução e leitura desta patente e postei é interessante...

反対から流すパートもなけりゃ分かんねーだろうが

Is it backwards?

I think human consciousness, is a tragic misstep in evolution. We became too self-aware, nature created an aspect of nature separate from itself, we are creatures that should not exist by natural law. We are things that labor under the illusion of having a self; an accretion of sensory, experience and feeling, programmed with total assurance that we are each somebody, when in fact everybody is nobody. Maybe the honorable thing for our species to do is deny our programming, stop reproducing, walk hand in hand into extinction, one last midnight - brothers and sisters opting out of a raw deal.

Kasper it is wrong design

В чем прикол?

Looks like Tesla played too much Pinball!!

This ´valve´design is flow dependant. Large flows = greater effect, low flow = virtually no effect.

It will be one way if you go from left to right

It doesn't fucking work.

why am i watching this shit at work... i am an interior designer, no need for tesla valves.

テスラバルブとは何をしたいものなの？水の流れをゆっくりに抑えることができるよということ？

これって水は流れてるわけで、逆止弁の代わりになるわけないよね。

is it possible to attach a turbine at the end to generate electricity

Didn't work. Needs more pressure and possible design revision.

Good job. Good luck with the channel.
