大功率透平机械叶栅流道的边界是相当复杂的.当采用圆柱坐标系时,对矩阵法和流线曲率法,需要单独处理流道边界上“破碎”的网格,这无疑增加了计算时间;如不处理则会降低计算精度.采用有限元素法虽然可以避免单独处理边界上的计算网格,但计算时间长和需要存贮单元多则是它的最大缺点.我们采用的在曲线坐标系中的流线曲率法和矩阵法既不必单独处理边界上的计算网格,也不要很多的存贮单元和过长的计算时间. 目前已发表的文章几乎都未涉及到将计算站设立在叶片流道内时,流线曲率法和矩 The boundary of high-power turbomachine cascade runners is rather complex, and when using a cylindrical coordinate system, the matrix method and the streamline curvature method require separate treatment of the “broken” grid on the boundary of the runner, which undoubtedly increases Calculate the time; if not processed will reduce the accuracy of the calculation. Although the use of finite element method can be avoided separately on the boundary of the computational grid, but the calculation time is long and requires more storage cells is its biggest drawback.We used in the curve Curvilinear curvature and matrix method in the coordinate system neither need to deal with the computational grid on the boundary alone, nor a lot of memory cells and too long calculation time. Already published articles almost did not involve the establishment of a computing station Curvature method and moment in flow path of vane
