首发时间:2016-08-29
摘要:应用CFD方法,结合标准k-ε湍流模型,利用非定常滑移网格(moving mesh)方法,对常规舵和扭曲舵在桨舵干扰情况下的水动力性能进行了计算;通过对不同进速下螺旋桨的推力系数曲线和舵的阻力曲线进行研究,同时结合舵表面的压力分布情况表明,扭曲舵在低速情况下可以起到节能的作用。

Hydrodynamic Performance Analysis of Twist Rudder
Abstract:A computational fluid dynamics(CFD) method, combind with RNG turbulence model and the moving mesh model, was used to calculate the hydrodynamic performance of normal rudder and twist rudder in the situation of propeller and rudder system. Through researching the force curves of the propeller and the rudder in different advance coefficient by calculation, combined with the analyzing of the pression distribution on the rudder. The results showed that the twist rudder can supply additional thrust and had the function of energy saving.
