| 摘 要： | 本文应用在连续生方程中增加压力对时间导数项的拟压缩性方法，数值求解三维定常不可压缩Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程。数值求解过程采用隐式的Ｂｅａｍ－Ｗａｒｍｉｎｇ近似因式分解格式。计算绕尖头旋成柱体的大迎角脱体涡流动，得到与实验相符的结果。

| Abstract: | The method of pseudo compressibility in which a time deriyatiye pressure term is introduced into the mass conservation equation has been used for numerically solving the three-dimensional steady incompressible Navier-Stokes equations. The solution procedure employs BeamWarming implicit approximate factorization scheme. The laminar incompressible Navier-Stokes equations is used to numerically simulate high incidence. vortical flows about a tangent-ogiye-cylinder, the numerical results are in good agreement with experiment. |
