An interface-capturing method is used to describe the relativistic dynamics of a twophase flow. Following Allaire, Clerc and Kokh, we are able to build a seven-equation model of conservation equations for particle number density of each fluid component, for the energy-momentum tensor of the mixture and an advection equation for the volume fraction of one of the two fluids. The relativistic model of such a mixture needs an additional law in order to get a closure. We study two dierent closure laws: isobaric and isothermal closure.

Abstract

An interface-capturing method is used to describe the relativistic dynamics of a twophase flow. Following Allaire, Clerc and Kokh, we are able to build a seven-equation model of conservation equations for particle number density of each fluid component, for the energy-momentum tensor of the mixture and an advection equation for the volume fraction of one of the two fluids. The relativistic model of such a mixture needs an additional law in order to get a closure. We study two dierent closure laws: isobaric and isothermal closure. The weak discontinuities propagating in the mixture for both models are examined.
