摘要: 采用RNG (Re-Normalisation Group)k-ε两方程模型对前置定子导管桨湍流特性进行数值模拟,并分析其水动力性能.通过与试验结果和势流理论结果的对比,验证了黏流理论预报结果的准确性和有效性.对不同定子安装角、不同定子翼型切面厚度以及不同定子叶片数目的前置定子导管桨敞水性能进行黏流理论预报,并分析了这些几何参数对前置定子导管桨性能的影响规律.

Abstract: The turbulent characteristics of ducted propeller with pre-swirl stators were simulated numerically and the hydrodynamic performance was analyzed by RNG (ReNormalisation Group) k-ε viscous model. Compared with experimental and potential data, the numerical results are accurate and efficient. Furthermore open water performance of propulsion with different setting angle, section thickness and number of stator blades were predicted numerically. The effect of geometrical parameters on hydrodynamic performance was analyzed.

Key words: ducted propeller, pre-swirl stators, setting angle of stators, efficiency
