摘要
针对StegerWarming流通矢量分裂格式和其修正格式所构成的混合格式进行了研究,引入压差放大因子,使其对于有粘激波流场分辨能力有所提高,同时采用一种特殊分裂方法以简化矩阵运算。利用该方法研究了三种超声速流场:(1)平面激波反射问题;(2)超声速边界层流动;(3)高超声速压缩拐角流动。
A hybird scheme is constructed by Steger Warming Splitting and its modified algorithm. The enlargment factor of pressure difference is used to prompt ability of flow field resolution.Meanwhile, a special matrix splitting method is adopted and makes matrices very easy to compute. Three examples of two dimensional fluid flows containing shocks and/or boundary layer demonstrate the efficiency and accuracy of this new scheme.
