Abstract

Abstract

Based on the verification of the accuracy of numerical simulation and grid size,it was simulated the internal explosion of an cuboid using Euler-FCT method and two-step simulation,taking account of multiple reflections.It was studied the cavity effect of doors and windows,the effect of the windowsill high and window size on blast wave propagation,and also analysed the result.Cavity effect has a great impact on blast wave propagation which can not be ignored.Window size has a certain influence on blast wave propagation,and the effect of windowsill height is relatively small.
