Abstract

In this paper, we present a two fluid mixing model based on hyperbolic equations having complete state variables (velocity, pressure, temperature) for each fluid. The numerical algorithm is an extension of a front tracking method from microdynamics to macrodynamics. The numerical results are validated by comparison to the incompressible limit. 1 Introduction Fluid mixing is important to science and technology, for example in the evolution of supernova explosions, pipeline flow and the performance of inertial confinement fusion reactors; it is important to the description of natural phenomena, as in meteorological temperature inversion driven updrafts and the geological evolution of salt dome formations. We are concerned with the dynamic growth of a thin mixing layer formed at the interface between
