WebRegimes. Hypersonic flow can be approximately separated into a number of regimes. The selection of these regimes is rough, due to the blurring of the boundaries where a particular effect can be found. [citation needed] Perfect gas. In this regime, the gas can be regarded as an ideal gas. Flow in this regime is still Mach number dependent. Classic study of fluid dynamics concentrates on the flow of a single homogeneous phase, e.g., water, air, steam. All of the fluid flow equations and relationships discussed normally in this section are for the flow of a single phase of fluid whether liquid or vapor. When at certain important locations in fluid flow … See more By definition, multiphase flow is the interactive flow of two or more distinct phases with common interfaces in, say, a conduit. Each phase, … See more All multiphase flow problems have features which are characteristically different from those found in single-phase problems. 1.
