Thanks for the time of your's, it was more then just helpful

[@systemerror-tg2dx]

can it create vibrations due to vortices generated in divergent flow?

[@TheCarpenterUnion]

I think you over estimated the amount of steps Tesla would have taken to developing this. It is trivial to realize that forcing fluid back on itself will cause a high reduction in flow. To me it seems the first step would be to start with a series of the lobes that we see, then adjust the angles between them to be optimal, rather than what was displayed in the video. Granted, your intent may have been to demonstrate the way a modern engineer would approach the problem, which would have been fine had you not portrayed it as Tesla's design process.

[@puckspirit2573]

I'm actually considering to use it in a work application. Could someone help? The thing is, we have a centrifugal pump with DN70 inlet, sucking fuel from a tank. But we also need to create pressure in front of it, using a specific gear pump. We tried using conventional one way valves to keep gear pump from just sending fuel through a loop, but it ends up just closing them and suffocating the centrifugal pump. Will Tesla valve work in this scenario, when you have a flow going one direction, but pressure is coming from the other one. Seems kinda impossible when put into words, but I hoope there's someone here, who can help

[@deathskayebolo6806]

What happens with superfluid if you use and expansion chamber between two of those valvular conduits ? Would superfluidity prevent the turbulence or not? Some one need to test this, cause we will soon realise Space might actually be superfluid ocean in wich planet floats.

[@lick28]

Can you show the difference of water speed in a valve? It's an animation based on laws that are accepted. Like animating an object falling because we know gravity exists. Jesus

[@guywiththebottle]

@@lick28 His point was that you can animate anything. You can animate the valve breaking from excess pressure. You can animate an anvil falling on it. You can animate glitter coming out of the other end. You can also animate generally accepted "laws" in the logic of children's cartoons but that does not make them real nor evidence of any kind of "laws". And yes, you can show the difference of water speed in a valve. Today we have plastics and glass to make small scale low pressure valves. We also 3D printers and pressure gauges. I am surprised that a reasonable person would suggest that the only way to demonstrate how a valve works would be through computer animations. Because we all know the significance of computer animations when Nikola Tesla made the valve in question...

It's also much easier to just animate something we know to be the effect of a certain action than to go out of our way to waste physical resources like water and money. It's also easier to articulate how the inner workings of something goes in an animation as you can highlight the important things to be noted. Complaining about the fact that it's animated in this context seems very nitpicky

Is it a waste of physical resources to teach people about valves? You can highlight whatever you want in an animation, that was the point of the critique. Not sure why it would be nitpicky that the guy expresses that he would be more convinced by a recording of a stream of water rather than a simulation of a stream of water.

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.

[@prjndigo]

its a solid state oscillating pump, remember he was working on pumps

[@oscarwoodly7392]

I wonder if there’s a lower threshold whereby if the input is slow enough, the various divergences and vortices are minimised, therefore the the output would be increased compared to if you had a higher input (which would seem to create more restrictive flow?)

[@VenhaVerIsto]

@@oscarwoodly7392 i was wondering the same, anyone got answers?

[@walterbrownstone8017]

There's probably a fairly linear relationship between input pressure and output volume.

I think you are right. It’s a simple and robust way to meter something using higher pressures elsewhere. It really can’t stop flow because it relies on the dynamics of flow to even work.

A small ball check valve easily handles the job.

[@solapowsj25]

@@sircrapalot9954 Application of newer technology is much needed. A train 🚂🚋🚃🚋🚃🚋🚃in a tunnel with walls that reflect the divergent air on to the rear of the train would have twice the efficiency of trains today. Using turbo jets to clear air from the front would prevent wind resistance in the tunnel while additional forward thrust is developed. Directing this displaced jet of air on to a modified Tesla mechanism on the tunnel walls to redirect the air jet on to the rear of the train would again add forward thrust. This is significant since wind resistance at 100 mph is equal to the weight force of the average vehicle. Also, the hyperloop intended to remove air resistance by creating partial vacuum in a tube is more dangerous than the Titanic. Lastly, Tesla has been successfully tested in jet and rocket propulsion.

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.

Thus the force in the following secondary valve is increased, helping it to slow down the main stream even more.

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.

[@aydengonzalez9786]

That’s not necessarily a bad thing. When you have low flow and low pressure, the moving parts associated with a true one-way valve will be less likely to fail and will have less associated wear.

@Palo Kan Yes, because in such a place a total valve is not needed a flow decrease is enough. If the answer to the proposed question had actually been "yes" the only places the other valves would have stayed would be if there wouldn't have been enough room for the tesla valve, but as it turns out it only replaced the valves in a few places where a flow decrease is enough, the vast majority of tradition moving parts valves were not replaces because they need to shut the water completely

Has anyone ever tried to make a firearm silencer in the shape of a tesla valve? I'm interested to know how well it would work at slowing down gasses and whether the moving projectile blocking the primary flow channels would effect it as it travels down the valve. However my instincts are telling me the gasses would just push the projectile downward in the direction of each curve and it would probably just blow up lol.

[@roomtemp6374]

It's not designed to be a constant pressure valve. Under pulsing conditions, and with the right size/length conduits for the density of the fluid and pulse width, it effectively does block flow completely. Think reed valve, not water faucet.

One thing that would be worth mentioning is that Tesla's design relies a lot on Bernoulli's principle. The trade off, in this application, is between pressure and speed. The speed is determined by the Coandă effect. According to the definition, if a fluid meets a curved surface, in our case the added obstructions, it will attempt to follow it. When this happens, the fluid that needs to travel further on the encountered obstruction will speed up (and drop in pressure), resulting in a higher velocity, which will result in the diverging stream clashing with the main stream, obstructing it

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.

That’s what I was thinking. For a sump pump check valve. Only problem is those are supposed to be vertically integrated. But I would imagine that the sound of it turning off would be drastically reduced if you put a couple 90 degree elbows just above the pump. It would of course need a traditional shut off valve below it though. I mean even the more expensive “quiet” is by no means quiet. And they break, too.

[@Robert_McGarry_Poems]

Tesla was intrigued by the idea that vibrations, so basically sound, had the capacity to mimic other chemical and physical reactions. Modern science now calls this study phonons. Later, he would update his ideas to include sonic resonances from many different phenomenon. This obviously influenced his work on radio and alternating current. And directed his ideas later in life about wireless electricity, through microwave transmission. He probably didn't have an understanding of microwaves yet, but that is what he was thinking about.

[@davidbaker9089]

I’m sure had Tesla directed more time and contemplation towards this valve , he would have incorporated a full stop application. But to serve as an indication of the type of mind Tesla possessed, he was at least as brilliant as Edison, if not more, and fit to sit at the table with Einstein

[@lordraj365]

Cant believe how his mind was capable of thinking like this. What a genius!

[@russellwalker3830]

It's really not that incredible. I can't understand how a person couldn't come up with this if you were specifically looking for a one way valve with no moving parts. The first image that enters the mind is surfaces or mechanisms which grip or engage in one direction. Like a ratchet or running shoes. Then your brain combines those forms with a pipe. Then it see this would not work as is or at best provide very minimal extra resistance in one direction. Then your brain says, how can we increase the resistance? And it answers itself and says by creating a secondary flowpaths which apposes the primary.

[@guywiththebottle]

What really bothers me is that if somebody did something similar today, you wouldn't care. You care because Nikola Tesla did it. Because of his other inventions. You also care because somebody slapped the letters Tesla on a billion dollar company and now anything related is amazing. The guy asked himself how to restrict water flow. All you need is a material for water to run through and move things around until you are satisfied. Then, you show it to the public with little success because the market did not need the solution or your sales pitch was weak. Then, you die and wait until somebody makes a company with your name on it and an organisation decides to use a handful of valves using your design. That is how you make a Tesla valve. No advanced formulas, no string theories, just carve out some wood and drive some water through it. Alternatively, replace the wood with clay.
