隐式TVD格式在气液两相爆轰数值模拟中的应用

为研究ＦＡＥ（燃料－空气炸药）爆炸参数规律，运用二维敢液两相方程组模型，针对其中的气相方程组采用高分辨率的隐式ＴＶＤ格式，液相方程组采用ＭａｃＣｏｒｍａｃｋ格式，较好地对ＦＡＥ气液两相爆轰产生的爆轰波的发展和传播过程进行了数值模拟，计算结果与国内外的研究结果符合良好。

Implicit TVD Schemes Applied to Gas-Droplet Detonation Calculation

In order to investigate parameters of FAE (fuel air explosive) explosion, the two_phase gas_droplet conservation equations with two_dimensional axial symmetry in the Euler coordinate were used. High_resolution implicit TVD (total variation diminishing) schemes were applied to gas phase equations and MacCormack schemes to liquid equations. The formation and propagation of gas_droplet detonation wave were simulated numerically. The simulation results and the others are compared with a good agreement.
