边界层分离流边值问题的算法研究
Bordering Algorithm for Solution of Boundary layer Separation Flow
【摘要】 本文给出边界层反方法边值问题的一种快速求解方法。该方法可用于二维与三维问题。它是在正方法边界层算法的基础之上增加了一个矩阵算法,该矩阵很容易求逆,总的CPU时间仅增加约20%,使用该算法对反方法问题求解和进行数值稳定性分析都将十分方便。
【Abstract】 In this paper,a quick solution method for the bordering algorithm of the boundary layer equations in inverse mode is given.The method applies to the 2 dimensional as well as to the 3 dimensional problems.This algorithm appears to add an extra matrix operator to the boundary layer algorithm in direct mode.The matrix is easy to inverse,so the global CPU time needed to increase is only by 20%.This algorithm seems to be very useful not only for solving equations, but also for analyzing the numerical stability characters of the boundary layer equations in inverse mode.
