Reflection of an air shock wave from a foam layer

Within the framework of an equilibrium model of disperse media, the problem on reflection of an air shock wave from a foam layer located in the neighborhood of a rigid wall is investigated. An exact solution is constructed for the initial stage of reflection from a homogeneous layer. The effect of the type of gas which fills foam bubbles on the characteristics of reflected waves is studied. The results of numerical calculations are given, which are obtained using the modified Godunov method.
