高效扭曲舵的水动力特性数值分析

Numerical analysis of hydrodynamic characteristics of an efficient twisting rudder

传统船舵在船舶螺旋桨流程的影响下会产生空泡效应,造成船舵结构的损坏和转向功率的下降,造成船舶运营成本的提高。为了解决这一问题,行业内针对高效扭曲舵的研究成为一项热点。不同于传统舵,扭矩舵具有更好的水动力特性,能够克服船舶螺旋桨的尾流影响。本文的研究方向是对高效扭曲舵的水动力学特性进行理论分析和仿真,实现扭曲舵的最优参数设计,对于改善现有船舵的性能有一定的指导意义。

Traditional rudder will produce cavitation effect under the influence of ship propeller flow,resulting in the damage of rudder structure and the decrease of steering power,resulting in the increase of ship operation cost.In order to solve this problem,the research on efficient twisting rudder has become a hot topic in the industry.Unlike traditional rudder,torque rudder has better hydrodynamic characteristics and can overcome the influence of ship propeller wake.The research direction of this paper is to carry out theoretical analysis and simulation of hydrodynamic characteristics of efficient twisting rudder,and realize optimal parameter design of twisting rudder,which has certain guiding significance for improving the performance of existing ship rudder.
