Numerical Simulation of Hot Shock Wave in Porous Aluminum

In this paper, hot shock wave produced by X-ray radiation in porous aluminum was studied by numerical simulation method. GRAY's three-phase equation of state was used to describe the material states. By improving the widely used p-a relation, we get a better form to describe porous material states. Further more, we revised the spherical shell model of porous material and used it in hot radiation problem to describe the constitution relation of p and a. On the whole, we established a new set of equations to handle the problem we interested in and get some useful results.
