摘要: 本文采用了有限差分方法——TVD格式(Total Variation Diminishing,A.Harten,1983)对燃料蒸气云爆炸产生的二维轴对称爆炸场进行了数值模拟。爆炸波超压和运动轨迹的数值计算值与实验结果吻合得相当好。

Abstract: In this paper, Total Variation Diminishing (TVD) scheme was used to simulate the two-dimensional axisymmetric blast fields from explosions of fuel vapour cloud. Numerical solution fo overpressures and trajectories of blast waves are agreement with the experimental results.

Key words: fuel vapour cloud explosion, blast fields, numerical simulation
