Abstract

The paper suggests a numerical implementation of boundary conditions at permeable boundaries for gasdynamics equations. The main peculiarity of the approach is that the basic and additional relations at the boundary are written in incremental form, not in integral one. Such technique on the one hand increases robustness of the numerical simulation, and on the other hand simplifies boundary conditions treatment for flows of gas with complex state equations
