Equation (3) is based on the measured values of void fraction at Oklahoma State University, TwoPhase … The phase velocity of a wave is the rate at which the wave propagates in any medium. This is the velocity at which the phase of any one frequency component of the wave travels. For such a component, any given phase of the wave (for example, the crest) will appear to travel at the phase velocity. The phase velocity is … See more The group velocity of a collection of waves is defined as $${\displaystyle v_{g}={\frac {\partial \omega }{\partial k}}.}$$ When multiple sinusoidal waves are propagating … See more • Cherenkov radiation • Dispersion (optics) • Group velocity • Propagation delay See more In the context of electromagnetics and optics, the frequency is some function ω(k) of the wave number, so in general, the phase velocity and the group velocity depend on specific medium and frequency.

WebThe result is a two phase mixture (vapor and liquid) at the valve outlet and in the downstream piping. Velocity of this two phase flow is usually very high and results in the possibility for erosion of the valve and piping components. Choked Flow Choked flow occurs in gases and vapors when the fluid velocity reaches sonic values at any point in ...
