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。
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.
