提出了一种在模拟盆地中利用多段波发生器产生冲洗波的方法。在这种方法中，波浪发生器是由波浪高度和自由表面上的冲刷波的表面横向速度组成的波浪发生数据控制的。波浪产生的数据是由Navier-Stokes计算的结果制备的。对全船和细船在不同航速下的冲浪进行了模拟，研究了船型和航速对冲浪的影响。计算结果较好地反映了细船和满船在不同航速下产生的波场特征。在日本国立海洋研究所进行了多节段波浪发生器产生洗涤波的实验。冲洗波产生的结果表明，波浪高和波长与计算值吻合较好。实验结果表明了该方法的有效性。
A generation method of wash wave by using multi-segmented wave generators in model basin is proposed. In this method, wave generators are controlled by the wave generation data consisting of wave elevation and surface lateral velocity of wash wave on the free surface. The wave generation data are prepared by the results of Navier-Stokes computation for wash wave. Wash waves are simulated for full and fine ships with various speeds was carried out to investigate the influence of ship types and ship speeds on wash wave. The computed results give a good account of the characteristics of wave fields generated by fine and full ships with the various ship speeds. Wash wave generation by multi-segmented wave generators were carried out at the National Maritime Research Institute in Japan. The results of wash wave generation demonstrate that wave height and wave length are in good agreement with computed one. The results indicate the effectiveness of this wash wave generation method.
