超声速化学反应流场迎风格式数值模拟及并行计算

1、超声速化学反应流场迎风格式数值模拟及并行计算 基于有限体积迎风格式对超声速燃烧流场进行了的数值模拟。由于超声速燃烧流场绕流的简单性,要求对多组分eulerns方程求解的数值模拟方法应具有较高的计算精度及效率。本文引用帮助点方法建立了具有空间二阶精度的vanleer迎风矢通量分裂格式,并应用于超声速燃烧流场绕流的数值模拟。化学反应为氢气空气+反应模型,采纳考虑了化学反应特征时间的当地时间步长显式rungeku 维普资讯 s p 2 0 e .0 7 trn a t n fna j gunv riyo r n u is asr n u is a s ci so ni iest f o n aeo
