提出了一种预测高速排水船运动特性的数值方法。该方法基于高速细长体理论，即2.5维理论，其中自由面条件为3维，控制方程和体表条件为2 D，采用瞬时自由面格林函数建立体表积分方程组。将数值预测结果与单壳NPL船的试验结果以及条带法的理论结果进行了比较。结果表明，该方法能较好地预测高速排水船的运动响应特性。
A numerical method is presented for predicting the motion characteristics of high speed displacement vessels. The method is based on a high speed slender body theory, 2.5 D theory, where the free surface condition is 3 D, but the control equation and body surface condition are 2 D. The transient free surface Green function was used to formulate the integral equation on the body surface. The numerical predictions were compared with experiment results using a mono hull NPL ship, as well as theoretical results by the strip method. The results show that the method can satisfactorily predict the motion response characteristics for high speed displacement vessels.
