    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.
    I came across only one YT video where the guy understood the Tesla valve. ruclips.net/video/SQAlM5Nyu9Q/видео.html

      Thank you for stating that. I've thought the same thing and thought it would make for a great underfloor on a performance car with some modifications. The potential ground effects could be massive if properly designed
