Research on 3D Eulerian numerical simulation for explosion

A multi-fluid-mesh 3D-Eulerian method and JWL state equations were presented. With the program MMIC3D programmed in FORTRAN, the characteristic of shock wave spreading in buildings and workshop equipped with windows was simulated, furthermore, the effect of decompression was showed. With the software VISC2D and VIS3D, the flash pictures and analysis of the result data were made. The calculating example of infinite boundary air explosion has been examined whose result data are mostly matched with the experience data, which can show the feasibility of the method.
