摘　　要：利用MAC（marker and cell）法直接数值求解连续方程和N-S方程.为模拟不规则波长时段连续造波及消除波浪遇结构物后形成的二次反射,采用了源造波法.对开敞边界,采用了海绵阻尼消波和Sommerfeld条件相结合的处理方式.MAC (marker and cell)method is applied to solve the N - S equation and continuity equation numerically. In order to simulate successive long-time wave generation of irregular waves and absorb the reflected waves from a structure, the source generation of waves is applied. A sponge layer for wave damping absorber combined with the Sommerfeld radiation is used to the open boundary.
