摘要
通过有限差分方法（ＭＡＣ－ＡＦ１）求解时间相关的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程，对旋转矩形通道中粘性流动进行了数值研究，旋转轴方向与主流方向垂直，给出了充分发展时矩形通道中的二次流结构及主流速度分布，得到的数值解与实验吻合良好。
In this paper,in order to take the numerical simulation of fully developedviscous flow in a rotating rectangular duct,numerical algorithm MAC-AFl is employedto solve primitive incompressible unsteady Navier-Stokes equation.The numerical results contain secondary flow structures and velocity profiles along the horizontal centreline and the vertical centreline of the duct,existing experimental with numerical resultsis quite favourable.
