摘要: 将对接分区网格与分区求解算法结合,有效地求解了带副翼偏转的翼身组合体绕流的N S方程.数值方法中选用VanLeer分裂格式离散无粘通量项,采用中心差分格式来离散粘性通量项.分区交界面采用了一种满足通量守恒的内边界耦合条件.数值算例表明该方法是求解带操纵面偏转的翼身组合体绕流的有效方法.

关键词: N-S方程, 分区算法, 绕操纵面偏转流动

Abstract: In terms of the combination of patched grid and domain decomposition techniques, the N S equation of the complex flow around a wing body combination with deflection of control surface (aileron) is solved. In the computation Van Leer's scheme is employed to discretize the inviscid flux terms and the viscous flux terms are discretized by adopting central difference scheme. An internal coupling condition satisfying the conservation of flux is used on the interface of neighboring regions. Numerical results show that the present method is effective one for solving the flow around a wing body combination with control surface deflection.

Key words: N S equations, domain decomposition method, flow with control surface deflection
