摘　　要：作者采用时间相关法,通过有限体积离散,运用带化学反应的全N S方程,在神州巨型机上,针对试验模型,对油气比Φ=0.0和0.35的喷氢Scramjet燃烧室流场进行了三维并行数值模拟,得到了流场的精细结构。并行模拟所得壁面压力分布与试验所测得的壁面压力分布吻合较好。The conservation form of the NavierStokes equations with the addition of conservation of chemical species are solved using a LUSGS implicit finitevolume method. For the experimental model, the threedimension parallel study of a hydrogenfueled scramjet combustor of equivalence ratio Φ=0.0 and 0.35 has been performed on SHENGZHOU frame computer. Wall pressure comparisons between CFD and experiment show good agreement and detailed flowfields of combustion are also obtained.
