中文摘要:对水下航行体后带前置定子的导管桨片空泡和梢涡空泡起始进行研究。首先,采用基于混合网格的RANS求解器结合Singal空泡模型,数值模拟带前置定子导管桨片空泡形态,并与试验结果进行对比,预报的片空泡形态与试验结果吻合良好,表明用该方法预报水下航行体后带前置定子导管桨片空泡可行;其次,对水下航行体后带前置定子的导管桨多个方案全湿流动进行了数值模拟,通过梢部端面的最小压力值判断空泡起始,与试验结果进行比对,其吻合良好,表明可用该方法判别梢涡空泡起始。
英文摘要:In the paper, the research on sheet cavitation numerical predicted and estimation of tip vortex cavitation inception of ducted propeller with pre-swirl stator behind underwater vehicle is carried out. Firstly, the sheet cavitation shape of ducted propeller with pre-swirl stator was numerically simulated using a hybrid mesh based on RANS solver. A Singhal cavitation model based on transport equation was coupled in the RANS solver. The predicted sheet cavitation shapes were in good agreement with experimental observation. The overall results suggest that the present approach on predicting sheet cavitation shape of propeller behind underwater vehicle is practicable. Secondly, the wetted flow of ducted propeller with pre-swirl stator behind underwater vehicle is simulated, and the tip vortex cavitation inception is estimation based on the minimum pressure value on the propeller tip section, the results is also in good agreement with experimental results, it show that the approach on estimation of tip vortex cavitation inception is feasible.
