A Tesla valve is a fixed-geometry passive check valve. It allows a fluid to flow preferentially in one direction, without any single moving part.

The physics of Tesla Valve ⚛️

That's interesting, but note that there is a relatively wide, straight channel down the center for water flow. This structure was not designed as a valve so much as a flow restrictor, likely for flood mitigation. The more common "valve" design has no straight center path

I’m confused, what am I looking at

This is inside a Tesla??

Looks like it operates on Schauberger water flow principles

That is not a valve. It stops nothing. Looks more like a flow control.

I read a lot of confusion, so i’ve created a single picture that explains how it works. The Tesla valve creates a ‘lock’ made out of water instead of wood (the red stripe). You can see that, because of the ‘lock’ it creates a height difference which results in a waterfall after the ‘lock’ (in the blue circle).

Here's the explanation you're looking for: The Tesla valve, also known as the Tesla valve or Tesla diode, is a type of one-way valve invented by Sir Nikola Tesla. Unlike traditional mechanical check valves, the Tesla valve is a passive device that does not have any moving parts. Its design utilizes the geometry of a series of interconnected channels to create a highly asymmetrical flow resistance, allowing fluid to pass more easily in one direction than the other. *************************************************** Key Features of the Tesla Valve: 1. No Moving Parts: It relies purely on its geometric configuration to control fluid flow, which reduces wear and maintenance. 2. Asymmetrical Flow: The structure creates significantly more resistance to flow in one direction than in the other. 3. Robust Design: Because it has no moving parts, it is very durable and can operate in harsh environments. 4. Efficiency: It can be very effective in certain applications where traditional valves might be prone to failure or where minimizing mechanical complexity is desired. *************************************************** Applications: -Microfluidics: Often used in small-scale applications where precise control of fluid flow is necessary. -Heat Exchangers: Helps manage the flow of coolant in systems. -Chemical and Biomedical Devices: Used where passive, reliable fluid control is beneficial. -Pneumatics and Hydraulics: Applied in systems where reducing the number of moving parts can improve reliability and longevity. *************************************************** Design: The typical design involves a series of interconnected loops or chambers that create turbulence when fluid attempts to flow in the reverse direction, significantly increasing resistance. Forward flow encounters minimal resistance, making it much easier for the fluid to pass. *************************************************** Advantages: -Durability: No moving parts mean less maintenance and longer life. -Simplicity: Easy to incorporate into systems without complex control mechanisms. -Reliability: Works passively, so it is less prone to failure compared to mechanical valves. *************************************************** Challenges: -Flow Efficiency: In some cases, the forward flow efficiency might be less compared to mechanical check valves. -Pressure Drop: There can be a significant pressure drop across the valve even in the forward direction, depending on the specific design.

Here it clearly just slows the current.
