What's a practical use for the Tesla Valve? Are they in regular use anywhere today?

@RAW_Reality

4 жыл бұрын

@@Hickeroar This invention was never meant for typical "day to day" functions like that of use in hydraulics or other "pump"-like situations because it A) doesn't have a release, B) only is meant to directionalize flow, and C) won't prevent _ALL_ flow (of either direction). Also, it's not nearly as cost effective as the other forms of typical valve systems that exist, nor was it ever intended to be used as such. It pretty much only has a practical use in fluidics, which isn't what most people would even understand without a background in micro-engineering. It's effectively a diode, not a true "valve", as there are no flaps/points of full restriction, but typicallly most people don't care enough to fight for the name of "Tesla Diode" to the patent office. Also, it should be noted that this video does _not_ represent a "true" Tesla Valve's form, as the ports are misaligned, not at the correct internal depth, and the loop-backs aren't fully functioning as Nikola's design would have. Had they been a full "100%" replication, the gas flowing "back to front" through it likely wouldn't have traveled as far as it did. In Tesla's full design, restrictive force multiplies by a factor of 1.7x per rung, needing exponentially more force to travel further through.

When the flame is going in the "fast" route, it actually reminds me of the V3 cannon from WWII. That cannon worked by having propellant charges in side chambers along the barrel that were angled towards the muzzle and, as the projectile passed each pair of chambers, they'd ignite, giving additional force to the projectile. It seems the same could be happening, here. Each time the flame front passes by one of the teardrops, there's a secondary front that makes it's way around the rounded edge and then accelerates down the straightaway back into the main flow, but behind the main front, possibly adding more speed to it.

I loved when you said,”it’s actually louder” because in a way this is exactly how a ruffle suppressor works. The gases released by the combustion of the power is what’s causing most of the noise other than the projectile making its own dispersion of the air around it. A suppressor is kind of like a bunch of holes and stuff with a path for the bullet and so when the expanding gases exit the barrel they are slowed down by their own turbulent way of moving around and so the effectiveness just comes down to what design helps me release the pressure slow enough so suppress the noise but not decreasing velocity or compromising the unit

Sound is a relativity thing governed by particle state, in aircraft design its also there for the combustion, supersonic & hyper-sonic combustion. So everything you're hearing, which can be considered as loud from gun fire, is probably breaking the sound barrier including the combustion of the ammunitions fuel. eg; gunpowder combustion velocity and projectile velocity. Pressure and Temperature will also make a difference. Particle state is everything, up to and including charged particles traveling instantaneously (faster than light) around a pulsar star creating superluminal booms in an electron blue color via a vacuum known as the quantum vacuum. (pulsar emissions consist of Cherenkov radiation)

This makes me wonder about the benefits of incorporating the Tesla Valve into a rocket stove/thermo-mass heater.

I had seen the Tesla valve in one of his (Nikola Tesla's) drawings. While it is fairly easy to comprehend, it is so incredible to watch it in action. I would have never even thought about the fact that the flame front would accelerate in the opposite direction. I had been so focused on the fact that it would arrest the passage when trying to run backwards, that I didn't even think about it. He was operating on another plane of consciousness, to say the least. This was such a simple but elegant way to demonstrate his valve. It was thrilling for a mechanical/science nerd like myself to actually watch this demonstration. It reminded me of watching a feather fall like a rock inside of a vacuum chamber. It is so much better to witness than it is to read about. Thank you so much.

I suspect we would see something quite different with smoke and an air pump. I would also be really curious if we would see some periodic resonance in the flow at steady state or if it would just be random chaotic turbulent flow.

Some one have probably already meantion this fact, so here it probably goes again: In my study on fire and explosion saftey I learned that the flame front in a combustable gas mix will accelerate over a distance. The fun thing is that turbulence in the flame front will make the burn accelerate even faster and that is what you see happens. At one point it will reach a critical speed where the flame front is faster than the speed of sound in the medium/gas mix and the flame front will get a sudden increase in speed. This causes even more turbulence and even further accelerate the flame speed. The transition between subsonic and supersonic flame speed the flame goes from deflagration to detonation. Simply put, you go from a burning flame to an explosion 😀 So you do not need more tesla valves, you just need more stuff inn there with sharp edges to create turbulence and a longer tube. Try it out with a long plexi tube and you will get the same results. One empty and one with a lot of obstacles. This is one of the reasons why a gas explosion is so much more dangerous in a confined space with a lot of stuff/obstacles than out in the open. Been a few years since I studied this topic, so correct me if I remembered it incorrectly. -The random KZread mechanical engineer 🤘

Not exactly, you do not want to obstruct the flame so much that it can't continue, but yeah, the more turbulence you can create in the gas mix the faster the flame will burn. Objects with hard corners will do this as the burning flame front will push on the gas mix infront of it, speeding it up and thereby creating turbulence when the accelerating gas mix hits the objects and disrupt its flow. But it is the turbulence that is the key, so you are free to introduce it into the system however you like.

Hey so this happens to be something that is quite interesting in the combustion world. Flame acceleration is caused by a few things but a common thought is that turbulence and flame instabilities are driving forces in flame acceleration. As you wrinkle a flame it gets more surface area, which in turn increases the heat release rate, thus making the flame go faster. You can in fact accelerate a flame to very high speeds possibly even supersonic speeds. An interesting phenomenon is whats called Deflagration to Detonation Transition (DDT) where an accelerating flame can form into a detonation wave under the correct conditions. Its still not fully understood but definitely something interesting to look into. Thanks for making this video! A lot of interesting physics going on here.

If I recall correctly, in the video, the suppressor company owner says that the reason for this half and half split is that you want to bleed as much of the energy of the gas as possible before it exits the gun and suppressor. The most effective way of doing that is just a giant void, but you would need extremely long/large tube to reach subsonic speeds. So they compromise, by have the gas work against itself in the second half. At the time, it was hard to tell how much that affected the gas without something like this in context.

Man that tesla was one of a kind thanks for sharing your passion and making it easy and entertaining.

Someone else has probably pointed it out already, but: The same reason you noted for the valve system accelerating the expanding gas forward through the valve, also explains why the gas creates fast jets in reverse when you're forcing it backwards through the valve. The expanding gas front finds it easier to turn around and go through the valve "the right way", speeding up in the process.

I guess velve is the cool scientific way of saying valve.

I could binge watch your incredible videos all day. As a creator I'm constantly working on my cosplay projects with no 'downtime'.

However I think I made a mistake by leaving it out to dry, as it became very brittle, so on my next attempt I'll store in an airtight container. Sorry going off on a tangent there, but I just wanted to thank you as every video I've seen of yours has inspired me in many different ways and I'm pretty sure I can speak for many of your viewers when I say that.

@commonnons3ns316

No it wouldn't. A straight tube isn't a valve. It would be pointless. The demonstration was to show how the Tesla valve works by directional flow. An open flow or unrestricted flow, would be an uncontrolled flow. Valves are meant to control flow in one direction or another and/or increase or decrease pressure or volume of a fluid or gas in a conduit and/or a collection tank. An open conduit or vessel, simply allow a liquid or gas to flow freely and only be controlled by gravity or surrounding atmosphere. In other words... There is no comparison to be made unless your demonstration is on how a valve works in general. This demonstration is being made under the assumption that you already have basic knowledge of what valves are and what valves do.

Beautiful visualization of flow. Well done.

I'd love to see the extended valve video! Would the theorized increase in speed only apply to explosions? How are other elements impacted by the number, size, angle, etc. of leaflets?

High speed is not high enough and hence, the slow motion is not slow enough.

To understand the reason for the acceleration of the backward flow, remember that acceleration is calculated speed and velocity. The tear drop shape baffles force the medium to accelerate by forcing it to change direction. An object traveling in a circle is under constant acceleration. It’s been almost 20 years since high school physics, so I may be a little fuzzy.

This is cool, never hear of this until now.

This is truly Science, not a bunch of numbers, observation is the best base to understand anything

Don't forget the most important part. Surface friction of the fluid at the hook of each fin creates additional flow down the main line causing repeated stuttering of the pressure which, depending on the angle of the fin, will inhibit or perpetuate the main line.

which is why the fins are meant to be adjusted to the ideal angle for the desired performance of the main line in the intended medium.

I used to work for a company that needed liquid agitators to mix polymer with liquid sludge. The sludge was a homogeneous solution of water and solid particles. the polymer would bind the solid particles together and cause them to separate from the water and sink to the bottom. It was part of a water treatment process. An early stage that pulled all the solid particles out of the sludge. The polymer and sludge mixture needed time to mix before going to the next stage, which wasn't a big deal. The original design just had the mixture pumped through a series of 90 degree bends which created turbulence in the flow and mixed the solution on route in the hose. Then I discovered we didn't even need that most of the time if you purposely zig zagged the hose a bunch instead of having a straight shot. There were some projects that we had difficulty mixing the solution completely because the sludge was so thick it didn't mix enough even with a bunch of u bends and adding extra hoses and purposely creating an obstacle course of hoses up down all around giving it more time to mix. It still came out partially mixed. When I saw this design I immediately thought holy crap that's it! Force the flow backwards through that and it would create so much turbulence in the flow it would force the solution to mix for sure!

You needed a static mixer. They're a short chunk of pipe you put inline with the flow, with a steel mixing unit inside that doesn't have any moving parts. For a given length, the mixer guarantees a certain amount of mixing. It's very simple and common in all sorts of industries. And they are far easier to clean than a Tesla valve. Your old company must not have had any sort of engineers on staff if they didn't know about static mixers.

Very interesting how with the actual knowledge and computational power, countless processes, machines, inventions, etc. can be made more efficient, and this one, even though it is old, is surprising that new applications continue to be found and how a mind from more than 100 years old, continues to contribute to current technology. Love and hugs from Mexico 🫂😃🇲🇽❤️

Great editing on the last section! Beautiful visualization.

Hey, really nice visual presentation! I believe, just like in a pulse jet engine, the sub atmospheric pressure in the wake of the mainline flow accelerates the return loop flow. I agree with your prediction on burn acceleration to supersonic speeds. Pulse detonation engines use flow restriction coils called a Shchelkin spiral to transition from a simple combustion to detonation.

Flame speed is actually dependant on the mixing - the more (turbulent) mixing you get, the faster flame front will move. So here you are visualising two different phenomena at once, instead of just showing how Tesla valve works. You can show velocities much beter by just pushing a water filled with particles (pepper dust) and film their movement, from which you can calculate the actual velocities with internet available software. Basically a DIY PIV measurement (Particle Image Velocimetry) which real scientists use :) Admittedly though, flame propagation through it looks very cool!
