A multicomponent real-fluid fully compressible four-equation model for two-phase flow with phase change [PDF]

Physics of Fluids, 2019
A fully compressible four-equation model for multicomponent two-phase flow coupled with a real-fluid phase equilibrium-solver is suggested. It is composed of two mass, one momentum, and one energy balance equations under the mechanical and thermal equilibrium assumptions.

Absolute and convective instabilities in an inviscid compressible mixing layer [PDF]

, 2007
We consider the stability of a compressible shear flow separating two streams of different speeds and temperatures. The velocity and temperature profiles in this mixing layer are hyperbolic tangents.
