Introduction
It is well known that a shock wave can be attenuated when propagating through a porous barrier. Better understanding of this phenomenon is of significant importance in practical applications, e. g. in problems of industrial safety. As a result, the interaction of shock waves with a porous barrier has been studied in many papers. In particular, in [1, 2] a theoretical model, which assumes that a discontinuity breakdown happens at the moment when the propagating shock wave hits the barrier, has been developed. In accordance with this model the flow at large times is self-similar and the intensities of reflected and transmitted shock waves can be determined provided that some model is adopted for the flow through the barrier itself (typically it is considered as a steady subsonic flow).
