基于CFD方法的桨舵干扰非定常水动力性能研究
Unsteady Hydrodynamic Performance of Propeller and Rudder System Studied by CFD
结合标准k- 湍流模型,利用非定常滑移网格(moving mesh)方法预报了敞水螺旋桨和桨舵干扰的水动力性能,通过计算得出了不同进速下螺旋桨和舵的推力曲线,并进行比较,从中得出了一定的规律。同时给出了舵表面的压力分布图、桨舵干扰情况下的尾涡图和敞水情况下舵的尾涡图。计算结果表明,在有舵干扰时螺旋桨在均匀来流情况下产生的推力呈周期性分布,桨舵之间的干扰随进速的增加而逐渐增大。
ombined with standard turbulent model and moving mesh to do some research on the interaction between the propeller and rudder. Obtained the force curve of the propeller and rudder in different advance coefficient by calculation and got the regulations from them. And also show the pressure distribution on the rudder, the wake after rudder with propeller and without propeller. Results showed that the force of propeller and rudder were all fluctuated periodically, and the interaction between the propeller and rudder is increasing as the advance coefficient increased.
