摘要
针对一艘四桨推进的船舶,采用CFD数值仿真方法,分别模拟内、外桨位置变化后主船体及螺旋桨周围的流场,分析螺旋桨的布局,尤其是内、外桨横向、纵向距离的变化对螺旋桨推力系数、转矩系数、以及敞水效率的影响,提出船舶四桨布局的优化方向,给出四桨船布局优化的建议。
CFD method was employed to simulate the flow field while the position of inner and outer propellers was changed . The influence of propellers distribution on hydrodynamic performance , especially the influence on thrust coefficient , torque coeffi-cient and open water efficient was analyzed .Optimization principles of propellers distribution were presented .And some advices on propellers distribution were presented .
