均流中大型集装箱船桨舵干扰粘性流场的数值计算研究

Numerical study on the interaction between propeller and rudder of ultra-large container ship in uniform viscous flow

应用FLUENT软件的滑移网格技术,实现了均匀来流中的桨舵干扰粘性流场计算。考察了桨推力、舵受力,桨舵周围的速度、压力分布。为尝试预报舵空泡性能,还考察了桨舵间距变化对舵面上的压力分布的影响,取得了与舵空泡观察试验一致的结果。本项工作为船后桨舵干扰粘性流场计算提供了基础。

The moving mesh is successfully applied to simulate the interaction between the propeller and the rudder in viscous flow of mean inflow.The thrust of propeller,the force acting on the rudder and the distribution of velocity vector and pressure around the propeller and rudder are studied.The distance between the propeller and the rudder is changed to investigate the effect of this change on pressure distribution on the rudder. The cavitation on rudder is studied primarily, and the numerical results, are agreed with the observation in model test.This work provides a base for further study on the interaction between the propeller and the rudder after ship in viscous flow.
