摘要
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ＮａｖｉｅｒＳｔｏｋｅｓ（ＮＳ）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。
The block up coefficient technique is widely used to deal with irregular boundary shape due to its simple and highly accurate advantages.The present popular pressure velocity corrction algorithm and finite volume approach are proposed to numerically solve the complete Navier Stokes(N S)equations.The applicability,feasibility and key techniques in the calculations of this method for irregular especially multiobstacle boundary shape are systematically discussed.Numerical results are satisfying.
