| 摘 要： | 二维半理论是近年来应用于高速船舶运动和波浪载荷预报的一种势流理论.该理论采用了三维的自由面条件,控制方程和物面条件是二维的.新切片法则是目前在波浪载荷预报程序中广泛采用的一种二维势流方法.为了探讨二维半理论在船舶耐波性领域的应用,本文以NPL单体船船模Mode 15b为例,进行了二维半理论和切片理论在不同航速下的水动力,运动响应和垂向波浪载荷的数值结果比较,来说明两种理论方法的异同.

| Abstract: | In recent years 2-1/2D theory has been used for prediction of ship motions and wave loads where the free-surface condition is 3D but the control equation and body surface conditions are 2D.The N.S.M. theory is a strip theory where both the free-surface condition and the control equation are 2D. In order to investigate the application of 2-1/2D theory in ship seakeeping and wave loads prediction,a comparison was made between the results given by 2-1/2D theory and N.S.M. theory on different speeds taking the NPL ship models Mode 15b for example. The author wants to demonstrate the differences and similarities between the two strip theory. |
