【摘要】 本研究采用数值模拟方法系统地研究了全附体潜艇+螺旋桨水动力特性。利用RNGk-e湍流模型求解Reynolds平均Navier-Stokes方程,对带桨Suboff全附体模型的三维粘性流场进行了数值分析。在对全附体SUBOFF模型+螺旋桨水动力特性进行仿真分析前,对全附体SUBOFF模型的阻力预报结果与试验数据进行了比较,结果吻合,同时利用此模型对螺旋桨在非均匀进流条件下的推力和力矩的脉动特性进行了分析,清晰形象的描述了带桨全附体艇的水动力性能。更多还原

【Abstract】 This paper presents the researches of the authors in modeling and simulation of the appended submarine with 7-bladed propeller.Three-dimensional numerical simulations were conducted to observe the flow patterns and to measure the thrust and torque of propeller,as well as the resistance of submarine.In this paper,pressure distribution of blades and streamline around the propeller is shown.Moreover,the thrust and torque fluctuations of propeller with the non-uniform inflow were presented to show the flow characteristic of it.These results not only provided people with the access of understanding the flow pattern of appended submarine with 7-bladed propeller, but also were made to determine the methods which could be adopted to improve the performance of the propeller.Furthermore,the results of the analysis can be used in the design of low noise and high efficiency propeller.更多还原
