Two-dimensional effects of the head on interaction between planar shock wave with low density foam
Two-dimensional physical and numerical models for predicting the characteristics of the flow field during an unsteady interaction between a planar shock wave moving through air and a deformable saturated porous material were developed using the Representative Elementary Volume (REV) approach. The numerical model is based on a two-phase finite Arbitrary Lagrangian Eulerian (A.L.E) difference scheme for solving the two dimensional version of the governing equations. The numerical predictions are compared qualitatively and quantitatively to experimental results and good agreements are obtained both in one and two dimensional cases.
