COMPRESSIBLE GAS FLOW THROUGH THE DIFFUSIBLE BARRIERS AND THE POROUS MEDIA

This paper is focused on the numerical simulation of the compressible gas flow through the porous media and through the diffusible barriers. We work with the the non-stationary viscous compressible fluid flow, described by the RANS equations. The flow through the porous media is characterized by the loss of momentum. For the simulation of the diffusible barrier we analyze the modification of the Riemann problem with one-side initial condition, complemented with the Darcy's law and added inertial loss. The presented examples were obtained with the own-developed code for the solution of the compressible gas flow.
