Scientists have guessed how to use the century-old invention of Nikola Tesla
A Tesla valve is a pipe of a specific shape with many branches and side passages. The device stops passing water in the opposite direction when the level of turbulence of the liquid inside increases.
US scientists have established the principles of the check valve, which was invented by Nikola Tesla in 1916. The corresponding discovery was made by the staff of New York University. It turned out that the invention can pass water indefinitely in only one direction. This effect is observed due to the specific effect of turbulence on the fluid flows inside the device, reports the Independent.
According to New York University associate professor Leif Ristof, modern science for a long time could not answer the question of how the 100-year-old device works and in what areas of science and technology it can be used.
To find out, the scientists created a replica of a similar valve, tracking the direction of water at different speeds, pressures, and other flow parameters.
According to the researchers, the Tesla valve is a kind of switch that stops passing water in the opposite direction when the level of turbulence of the liquid inside it increases.
The Tesla valve can find practical application in the XXI century, scientists said. For example, to create various pumps used by car engines and industrial installations.
The Tesla valve is a type of check valve designed to allow flow in one direction, the design of which is made without moving parts. The principle of operation of the valve is that the flow passing through it in one direction is divided into flows that are directed in such a way that their kinetic energy is mutually damped, as a result of which a significant increase in the active resistance of the valve in this direction is provided. Named after Nikola Tesla, who invented this valve in 1916.
In addition to the design of the Tesla valve, this idea found application in another device — a mixer built on the Coanda effect.
