NUMERICAL INVESTIGATION OF THE PROPAGATION OF SHOCK-WAVES IN RIGID POROUS MATERIALS - DEVELOPMENT OF THE COMPUTER CODE AND COMPARISON WITH EXPERIMENTAL RESULTS

The governing equations of the flow field which is obtained when a the rmoelastic rigid porous medium is struck head-one by a shock wave are developed using the multiphase approach. The one-dimensional version o f these equations is solved numerically using a TVD-based numerical co de. The numerical predictions are compared to experimental results and good to excellent agreements are obtained for different porous materi als and a wide range of initial conditions.
