基于分块结构网格的泵喷推进器敞水性能模拟
|
摘要
为准确预报泵喷推进器的敞水性能,采用分块高质量结构化网格,结合SST k-ω模型对模型泵喷推进器进行数值模拟。结果表明:采用该数值方法所得计算值与试验值具有较好的一致性;进行泵喷推进器敞水性能模拟时,进口距转子域的最佳长度为3倍转子直径;泵喷推进器的前置定子有利于降低辐射线谱噪声和提高推进效率;较大的导管攻角有利于降低泵喷推进器的辐射线谱噪声。
In order to predict the open performance of pumpjet propeller, a numerical simulation of model pumpjet propeller is carried out using high quality block structured mesh and SST K-w turbulence model. The results show that the calculated value of this numerical method keeps consistent with the experimental value. The best inlet length away from the rotor domain is 3 times of the rotor diameter while performing the open performance of pumpjet propeller; the front stator of pumpjet propeller helps to reduce the radiation line-spectrum noise and promote the propulsive efficiency; designing the relatively big angle of attack of duct helps to reduce the radiation line-spectrum noise of pumpjet propeller.
