摘要

在惯性系下耦合求解非定常N-S方程和六自由度刚体动力学方程,对含有运动边界的复杂非定常流场进行了数值模拟,计算中采用动态嵌套网格技术,双时间方法结合Runge-Kutta显式时间推进进行数值求解。作为应用实例,数值模拟了矩形机翼刚性谐和振动以及外挂物投放的复杂非定常流场,计算结果同实验数据吻合较好,表明了数值方法的正确性和有效性。

Abstract

The unsteady N-S equations and 6dof rigid-body dynamics equations were coupled to solve on inertial coordinate system to simulate complicated unsteady flows with moving boundary, moving chimera grids were adopted and dual time stepping approach joined with explicit four stage Runge-Kutta method were used for computation. In order to verify the efficiency of the present method, unsteady flows about an oscillating rectangular wing and release of store were simulated. The computational results are in good agreement with experiment date from other literatures ·

Key words： dual-time stepping method; moving chimera grid; multi-body relative motion; unsteady N-S equation
