摘要: 采用多组分化学反应Euler方程组对驻定在高速飞行弹丸上的斜爆轰波流场进行了数值模拟。计算中分别采用TVD格式和基元反应模型，并基于并行编程模型MPI（message passing interface）实现了非结构网格上的并行计算，对流项和化学反应项用时间分裂法进行处理。计算结果表明并行计算能有效地提高计算速度，扩展计算规模，为进一步研究超驱爆轰推进技术奠定基础。

Abstract: TVD format and elementary reaction model are applied to the study of numerical simulation for phenomena of chemical non-equilibrium oblique detonation wave standing on a projectile. A parallel arithmetic based on MPI parallel environment on PC-Cluster system for the oblique detonation wave flow field is discussed. The results of parallel computation indicate that the parallel computation is practical and efficient for simulating the standing oblique detonation waves.
