| 摘 要： | 本文首先分析了中心型隐式格式和迎风型隐式格式的优缺点,在此基础上发展了一种自由参数可确定的反扩散隐式格式。用此格式计算了绕三维控制翼的层流和湍流分离流动。出发方程是三维简化N-S方程,用Baldwin-Lomax湍流模型。结果表明,这种隐式格式效率高,能满意地刻划流场。

| Abstract: | In this paper,the advantages and disadvantages of the central-differenced implicit schemes and the one-side differenced implicit schemes have been analyzed.Based upon the analysis an implicit anti-dissipative scheme of which the free parameters can be determined automatically has been developed.With the scheme we have calculated the three dimensional laminar and turbulent separated flows around the flap mounted on a flat plate.The governing equations are the simplified Navier-Stokes equations,and the two layer Baldwin-Lomax turbulent model is adopted.The results demonstrate that this implicit scheme can operate with a high efficiency and it can give the details of the flowfield with satisfaction. |
