摘要
基于 Warming 和 Beam 求解原参数方程的 AF 方法,提出了一种求解Navier-Stokes 方程的隐式近似因子分解格式,通过坐标变换,在计算域上进行方程离散并用时间推进法求解,湍流用代数涡旋粘性模型。对跨音速透平叶栅进行了试算,计算与实验结果吻合良好。
An implicit approx factoring scheme presented in this paper can be used to solve Navier- Stokes equations. An algebraic eddy viscosity model is used to simulate turbulent flow. By co- ordinate transition, discretization of the equations is done in the calculating region and a time - marching method is required for solving these equations. Several flow fields of transonic turbo- machinery cascades have been computed. The mumerieal results show good agreement with the experimental values.
