Linear interaction analysis applied to a mixture of two perfect gases

The linear interaction analysis is applied to mixtures of two perfect gases. Differences of molar mass and constant volume specific heat between both gases are taken into account as two new wave families. Transfer functions across the shock wave from these waves to acoustic, shear or entropy waves are given. The approach is validated against numerical simulations of the interaction of concentration spots with a shock wave. The case of turbulence creation by a shock wave traveling in an inhomogeneous mixture is considered. (c) 2005 American Institute of Physics.
