有限释能速率可燃气云爆炸场的研究

Studies on Combustible Cloud Explosion with Limited Energy Release

本文研究自由场中有限释能速率的可燃气云爆炸问题。并分别用能量均匀释放模型、能量波模型和ＴＶＤ格式对可燃气云爆炸场进行了数值模拟，得到了两种能量释放模型中显著影响爆炸场的控制参数。本文还对Ｍｆ＝１０的能量波模型和ｔｆ＝０．１的能量均匀释放模型的计算结果进行了对比分析。文中所用的方法可为实际气云爆炸场提供参数预测。

Combustible cloud explosion with limited energy release in free air is studied in this paper. Homogeneous energy release model, energy wave release model, and TVD scheme are used to simulate the combustible cloud explosion field. The control parameters that greatly affect the cloud explosion field are also investigated in each energy release model. Results of energy wave model in case of M f equals to 10 are compared to those got by homogeneous energy release model in case of t f equals to 0.1 in this paper. The method in this paper can be used to predict parameters of combustible cloud explosion.
