A five-equation model for compressible two-fluid flow is proposed, that is based on physical flow equations only. The model is conservative and pressure-oscillation free. Equations for continuous flow and jump conditions for discontinuities are given, as well as a discretization of the equations and an adaptation of the HLL Riemann solver to two-fluid flow. Numerical tests in 1D and 2D show the accuracy of the method.
