摘要
为了提高螺旋桨的推进效率,回收螺旋桨后大量旋转水流的能量损失,提出在桨后安装消涡助推叶轮,对螺旋桨和消涡助推叶轮组合系统进行敞水性能数值模拟,计算结果与螺旋桨敞水性能数值结果对比表明,加装消涡助推叶轮组合系统的推进效率提高9.113%。
In order to improve the propulsive efficiency of the propeller and recover the energy loss of a large amount of rotating water after the propeller,a hub vortex absorbed booster vane wheel behind the propeller was proposed.The open water performance of the propeller was numerically simulated by using the sliding grid method.Comparing the numerically results with the experimental values,it was found that the efficiency of the combined system with the hub vortex absorbed booster vane wheel is increased by 9.113%.
