【摘要】 提出一种隐式矢通量分裂差分格式并用来直接求解Ｒｅｙｎｏｌｄｓ平均Ｎ－Ｓ方程组。该方法避开了近似因子分解及矩阵运算，具有精度高、稳定性好、计算量少等优点。在平面叶栅跨音流场的计算中，较好地捕获了激波，与实验比较，结果令人满意。更多还原

【Abstract】 Implicit Flux Vector Splitting (IFVS) is provided to solve the Navier-Stokes equations.It can avoid approximate factorization or block-bidiagonal matrix,and has obvious superiority in enhancing accuracy、lessening amount of calculation、improving stability.In the calculation of flow field in 2-D transonic cascade,wave has been exactly captured and results are satisfactory.更多还原
