摘要
在流动分离的高雷诺数渐近理论“三层”理论的基础上,发展了一套计算二维定常不可压脱体分离三层结构的数值方法。采用相互作用程序控制方程组获得了椭圆型的数学结构,克服了传统边界层计算不能通过分离点的困难,得到了分离点附近的流场分布。计算结果令人满意。
A numerical calculation method for incompressible backaway separation flow is developed, based on the asymptotic triple-deck theory on the limit of large Reynolds number. By the using interaction model the equations near the separated point are elliptical, thus solving the difficulty that normal boundary layer theory can not go beyond the separated point. The results are satisfactory.
