大侧斜螺旋桨敞水性能分析

使用计算流体力学软件FLUENT模拟某大侧斜可调桨敞水的粘性流场,并计算其水动力性能。使用前处理软件GAMBIT建立螺旋桨实体模型并设定计算域和划分网格。选取若干进速,采用RNG模型进行计算,得到大侧斜桨的推力及其转矩,与试验结果比较分析,证明计算模型的可靠性,从而实现对螺旋桨的敞水粘性流场模拟,预报其敞水性能。

Analysis of Open Water Performance of the High-skew Propeller

The viscous flow of a high-skew adjustable-pitch propeller in open water was simulated by computational fluid dynamics software FLUENT,and its hydrodynamic performance was calculated.The computational domain and grids were generated by GAMBIT.By giving several advanced velocity and adopting RNG turbulence model,thrust and torque of the propeller were obtained.Comparing these datum with experimental results in open water,the reliability of computational model was proved.
