【摘要】 为了研究导管螺旋桨的推力、扭矩和敞水效率等主要水动力参数和进速系数之间的关系，本文采用物理模型试验和计算流体力学（Computational Fluid Dynamics, CFD）技术相结合的方式分析导管对螺旋桨水动力特性的影响。首先在本校拖曳水池开展导管螺旋桨模型的敞水性能试验然后使用计算流体软件STAR-CCM+对导管桨模型进行数值模拟。在模拟计算中应用多参考系法（Multi Reference Frames,MRF），分别采用不同湍流模型对导管螺旋桨的水动力性能进行计算，并与试验数据进行对比，验证了STAR-CCM+软件模拟可以对导管螺旋桨的水动力性能进行有效预报且使用SST k-ω湍流模型获得的水动力性能精度更高。研究结果表明，导管螺旋桨更适用于在低进速系数下工作的重载船舶。更多还原

【Abstract】 In order to study the investigate between the characteristic hydrodynamic parameters and the advance coefficient, this paper uses a combination of physical tests and Computational Fluid Dynamics(CFD) techniques to analyze the effect of the duct on the hydrodynamic characteristics of the propeller. Firstly, the open water performance test of the ducted propeller model was carried out in the towing tank of DLUT and then the numerical simulation of the ducted propeller model was carried out using the computational fluid software STAR-CCM+. In the simulation, Multi Reference Frames(MRF)method was applied to calculate the hydrodynamic performance of the ducted propeller using different turbulence models,and compared with the experimental data. It is verified that STAR-CCM+ software simulation can effectively predict the hydrodynamic performance of the ducted propeller and the accuracy of the hydrodynamic performance obtained by using SST k-ω turbulence model is higher. The results show that the ducted propeller is more suitable for ships operating at low advance coefficients.更多还原
