Web2.1 Homogeneous Equilibrium Model. One of the most widely used critical flow models is the Homogeneous Equilibrium Model (HEM) . This is primarily due to its simplicity. The HEM assumes there exists no difference between the liquid and vapor velocities within a continuum. Also, the two-phases are assumed to exist at the same temperature and ... WebApr 12, 2024 · Based on the two-dimensional hydrodynamic model of the finite volume method and structured multigrid, the flow characteristics around a square cylinder with boundary constraint are analysed. The gap ratio G/D (G is the distance from the cylinder to the channel boundary, and D is the side length of the square cylinder) does not change the …

Web1.5.7 Two-Phase Flow. Two-phase flow refers to the interactive flow of two distinct phases with common interfaces in a channel, with each phase representing a mass or volume of … 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.
