采用目前流行的压力速度修正算法，应用控制容积方法，数值求解完整的ＮａｖｉｅｒＳｔｏｋｅｓ（ＮＳ）方程。直接计算出流场的全部物理变量，系统地研究通度系数法在处理不规则边界尤其是多障碍物、边界类型复杂时的适应能力、可行性和计算过程中的一些关键性技术。结果表明：通度系数法即使在边界异常复杂时也能取得满意的结果 Adopting the popular pressure velocity correction algorithm, the NavierStokes (NS) equation is solved numerically using the control volume method. Directly calculate all the physical variables of the flow field and systematically study the adaptability, feasibility and some key technologies in the process of dealing with irregular boundaries, especially with multiple obstacles and complex boundary types. The results show that the pass coefficient method can achieve satisfactory results even when the boundaries are extremely complicated
