基于粘性流体理论,采用CFD技术数值预报双桨式吊舱推进器的敞水水动力性能。通过对某单桨吊舱推进器进行数值模拟,并与实验值进行比较,验证数值计算方法的准确性。最后数值计算了双桨式吊舱推进器在不同偏转角时的水动力性能,通过数值计算、结果比较和特性分析,计算结果呈现出一定的规律性,达到了给出双桨式全回转吊舱推进器数值预报的方法和一般性规律的目的,可以对此类推进器水动力性能的预报提供参考。
Based on viscous fluid theory, the hydrodynamics performance of tandem type pod propeller was discussed by using CFD technology. Then by numerical simulation of a single screw podded propulsor, and compared with the experimental results to verify the accuracy of numerical calculation method. The hydrodynamic performance of tandem type podded propulsor with different deflection angles is calculated by using the suitable numerical model and method. The results show an agreeable regularitywill provide reference for the prediction of hydrodynamic performance of tandem type podded propulsor.
