摘要
采用非正交曲线坐标系下的ＳＩＭＰＬＥ方法对含有稳定器的通道湍流流场进行了数值计算，网格采用分区方法生成，计算时对整个流场进行迭代计算而不需要分区迭代，避免了分区计算中界面上的插值计算．文中还对后台阶流动进行了计算，结果和实验比较吻合．
In this paper the turbulent flow is calculated in ducts with a stabilizer using SIMPLE method of generalized nonorthogonal curvilinear coordinate systems. Grid generation is performed by means of the zonal method. The iterative computation is conducted for the entire field instead of zonal iteration , which avoids interpolation on interface. The backstep flows are also calculated, the results showing agreement with experimental values.
