Abstract: We consider a 1D periodic system containing a large number of layers. Each layer is composed of two sub-layers of compressible fluids having different densities and equations of state. We present a comparison between a detailed numerical solution of the Euler equations that govern the multi-layer system, and two isentropic homogeneous (average) models effectively describing such a complex two-fluid mixture.
