摘要
用非定常面元法对拖式吊舱推进器的水动力性能进行求解,吊舱和螺旋桨的相互干扰通过诱导速度迭代处理.与将相互诱导速度在周向上进行平均的处理方法相比,文中的方法真实考虑了螺旋桨和吊舱相互影响的非定常性.为了节省计算时间和存储空间,对螺旋桨的求解只在主叶上进行.结果表明,该方法能够对吊舱推进器在均匀来流和在非均匀来流中的水动力性能进行计算.将敞水条件下的计算结果同试验结果进行了比较,两者有较好的一致性.
An unsteady surface panel method was used to calculate the tractor-type podded propeller＇s hydrodynamics performance. The interactions between propeller and pod are treated by the iterative calculation of induced velocity. In the iterative process, the unsteady interactions is taken into account. The propeller is solved only on the key blade in order to save calculation time and memory space. The method can calculate the hydrodynamics performance of propeller in uniform and non-uniform inflow. The calculation results were compared with open water test which are in good agreement.
