Implicit TVD Schemes Applied to Gas-Droplet Detonation Calculation

摘要: 为研究FAE(燃料-空气炸药)爆炸参数规律,运用二维轴对称气液两相方程组模型,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.

Abstract: In order to investigate parameters of FAE(fuelair 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.
