| 摘 要： | 以一条小方形系数常规双桨船、一条大方形系数常规双桨船和一条大方形系数双尾鳍船的试验计算为例,对双桨船采用三因次换算法进行了研究.研究表明:对常规双桨船,三因次换算法的形状因子k应采用裸船体阻力试验计算值;对双尾鳍船,三因次换算法得出的有效功率偏低,一般不宜采用.

| Abstract: | An investigation of applying three-dimensional extrapolation to twin-screw ship is presented in this paper, based on model tests and conversion of a conventional twin-screw ship with low block coefficient, a conventional twin-screw ship with high block coefficient and a full ship with twin- screw stern. It is concluded that the form factor k in three-dimensional extrapolation should take the value derived from naked hull resistance experiment for conventional twin-screw ship, whereas, the three-dimensional method with which the extrapolated efficient active power lowers unreasonably, is not appropriate for twin- screw ship generally. |
