A model of relativistic compressible two-phase mixture endowed with an equation of state (EOS) of general form is formulated. An interface-capturing approach is adopted in order to deduce the governing equations, i.e., the relativistic Euler equations of the flow field and a transport equation for the volume fraction at the interface. The two fluid components are assumed to have the same pressure and the same 4-velocity.

Abstract
A model of relativistic compressible two-phase mixture endowed with an equation of state (EOS) of general form is formulated. An interface-capturing approach is adopted in order to deduce the governing equations, i.e., the relativistic Euler equations of the flow field and a transport equation for the volume fraction at the interface. The two fluid components are assumed to have the same pressure and the same 4-velocity. Using a Mie-Gruneisen–type EOS, the thermodynamic properties of the mixture and the weak discontinuity waves are investigated.File in questo prodotto:
