【摘要】 本文用分块耦合的方法，并采用Ｓ．Ａｂｄａｌｌａｈ￣［１，２］和Ｍ．Ｌ．Ｍａｎｓｏｕ￣［３］的在非交错网格上隐式求解原始变量的Ｎａｖｉｅｒ－Ｓｔｏｋｅｓ方程的提法和离散格式，成功地解决了二维复杂流场的数值求解问题，获得了空腔流、Ｔ型叉管流、ＮＡＣＡ００２０翼型绕流和方块钝体绕流的稳态解，并进行了讨论。此方法还可推广到三维复杂流场的计算问题。更多还原

【Abstract】 This paper presents a domain-subdividing and matching me-thod for solving a complex 2-D viscous incompressible flow. An implicit scheme for the solution of N-S equations in primitive variables on non-staggered grid system,which developed by S. Abdallah￣[1,2]and M. L. Mansour￣[3], is adopted. Thc steady statfe resuIts of driven cavity flow,Tee-junction flow,flow past NACA0020 foil and flow past a rectangular obstacle are obtained and discussed. This method can also be advanced to complex 3-D flow.更多还原
