摘要
The accurate numerical simulation of air-blast is an industrial concern. Because the experimental investigation of these fast transient events is expensive and time-consuming, several numerical approaches of air explosion are carried out. In this paper, an air-blast simulation is described using Eulerian multi-material formulation. In order to validate the numerical approach and prove its ability for high pressure wave propagation, comparison of two examples with experimental results is performed. Both simulations lead to the same prediction for the pressure time history. Good agreement between the test results and the predicted pressure response is achieved. (C) 2005 Elsevier Ltd.
