摘要
采用 L U- AUSML W算法 ,对非线性双曲型 Euler方程进行求解 .该算法综合了 L U- SGS方法与 AUSMPW格式的优点 .为了验证 L U- AUSML W算法的有效性 ,在曲线坐标系中 ,对亚音速、跨音速和超音速流动进行了数值模拟 .
A LU AUSMPW algorithm is applied to solve nonlinear hyperbolic Euler equations, where the merits of implicit LU SGS method and high resolution AUSMPW scheme are associated. In order to verify the validity of LU AUSMPW algorithm, the nonlinear hyperbolic Euler equations describing subsonic, transonic, and supersonic flows are solved by numerical simulation in a curvilinear coordinate system. The computation results coincide well with those presented in literatures.
