| 摘 要： | 为了计算吊舱推进器的非定常水动力性能,建立了用诱导速度势处理吊舱和螺旋桨非定常相互干扰的方法,并和用诱导速度处理两者相互干扰的方法作了对比分析.讨论了两种方法的数值计算中为了避免奇异性而对一些参数的设定方法.经过用两种方法对均匀来流和非均匀来流条件下水动力性能的计算比较,发现两种方法的计算结果很接近,并与模型试验结果吻合得很好,但用诱导速度势的方法编程工作量较诱导速度方法少,而且还可节省大量的计算时间和存储空间,是一种计算吊舱推进器和其他组合推进器水动力性能相对简单而且有效的方法.

| Abstract: | An unsteady BEM is used to calculate unsteady hydrodynamic performance of the podded propeller.The interactions between the propeller and the pod are treated by two iterative calculation methods:induced velocity and induced velocity potential.The method of setting some parameters is discussed in order to avoid the singularity in calculation.Through the comparison of calculation results of two methods in the uniform and the non-uniform inflow,it is found that the results by two methods are very close. The ca... |
