Numerical investigation of the propagation of shock waves in rigid porous materials: Solution of the Riemann problem Academic Article uri icon


  • Presents a numerical solution to the Riemann problem inside a porous material using a TVD- based computer code which was developed during the investigation of the head-on collision of planar shock waves with rigid porous materials. The numerical solution revealed that although the compaction wave propagates with a constant velocity, the flow field induced by it is not self-similar. Since such a problem cannot be set up in a conventional shock tube, the present study should be considered as a theoretical one.
