Abstract: A high-resolution interface tracking method is applied to simulate compressible multi-fluid flows with general equation of state in one-dimension. It captures the interface by using Level Set technique with conservative numerical discretization at interface. It uses high-order PPM scheme and two-shock approximation for GEOS Riemann problem. Results show that the computation is high-order accurate and there are no numerical oscillation and smearing at multi-fluid interface.

Key words: compressible multi-fluid flows, general equation of state, interface-tracking method, high-order Godunov scheme
