摘　　要：发展了基于二维半理论的预报排水型单体船在波浪上的水动力特征及运动性能的方法。采用横向流方法对常规高速排水型单体船所受的粘性影响进行修正。在考虑粘性影响和航行姿态的条件下,对NPL系列单体船和SER IES64单体船型的运动性能作了理论预报,并与船模试验结果和势流理论预报结果作了比较。结果表明:考虑粘性影响能够在一定程度上降低高速常规排水型船舶运动预报的峰值,而航行姿态对其影响不大。A method for predicting the hydrodynamic property and motion of high-speed displacement monohull ship based on 2.5D theory is pressented. The cross flow method is used to estimate the viscous effects on conventional high-speed displacement ship. Numerical prediction results concerned about the viscosity are compared with the experiment results of NPL series mono-hull and SERIES 64 mono- hull, as well as with the results calculated by potential flow theory. It is found that viscous effects can decrease the peak value of conventional high-speed displacement ship＇s motion, but the effect of bow up state is not significant.
