基于船舶保向性的协同控制扰流舵水动力特性
Hydrodynamic characteristics of collaborative spoiled rudder based on course keeping purpose
摘要
Abstract
To obtain the course-keeping characteristics of the collaborative spoiled rudder,the numerical model for predicting the hydrodynamic performance of ship rudders was constructed using viscous flow computational fluid dynamics(CFD)technology.The grid independence analysis was carried out for the corresponding conventional rudder,and the optimal grid partitioning strategy was determined.The accuracy of the numerical method was verified based on experimental data.Based on the flexible and controllable characteristics of the spoilers of collaborative spoiled rudder,the spoiler open angle could be adjusted in the non-steering state to obtain the hydrodynamic performance of the rudder.Results show that the lift,drag and spoiler stock torque increase overall as the spoiler open angle increases,while the lift to drag ratio shows a significant trend of increasing first and then decreasing with the increase of the spoiler open angle.The maximum lift to drag ratio of 4.81 is obtained at the rudder angle of 16°.The same course keeping lift and similar efficiency as the conventional rudder can be obtained by adjusting the spoiler open angle.关键词
