WebWe give an account of the analogies between the Nash– Kuiper C solutions of the isometric embedding problem and the weak solutions of the incompressible Euler equations which violate the energy conservation. Such analogies have lead to the recent resolution of a well-known conjecture of Lars Onsager in the theory of fully developed turbulence. 1. The … WebThe origin of the idea of vapor quality was derived from the origins of thermodynamics, where an important application was the steam engine.Low quality steam would contain a high moisture percentage and therefore damage components more easily.
