The control equation are the N-S equation , Baldwin-Lomaxturbulence model. The discrete of equation is finite volume control way to solute directly. Used the multi-grid and remnant polished technique to accelerate the convergence.

• 控制方程采用直角坐标系下的 N-S 方程组、Baldwin-Lomax 湍流模型,方程的离散采用有限体积控制法中心差分格式直接加以求解,采用了多重网格技术和残差光顺等技术来加速收敛。
