摘要
随着喷水推进器的快速发展,除了在传统高速船舶上得到大量应用外,在中低速船舶上的应用也得到越来越多关注。首先介绍了喷水推进器的发展历程及工作原理,接着介绍在中低速船舶应用优势及实际应用情况,最后采用计算流体动力学(CFD)方法对进口流道倾斜角在中低速船典型工况下进行优化分析。结果表明,当进口流道倾斜角α为33°时,损失系数较小,效率较高,抗空化性能好。
With the rapid development of waterjet propulsion,in addition to the large number in applications on traditional high-speed ships,the application on medium and low-speed ships has also received more and more attention.This paper firstly introduces the development history and working principle of waterjet propulsion,then introduces the advantages of application in medium and low-speed ships and the actual application,and finally adopts the computational fluid dynamics(CFD)method to optimize the inclination angle of the inlet duct in the typical working conditions of medium and low-speed ships.The results show that when the inlet duct inclination angle is 33°,the loss coefficient is smaller,the efficiency is higher and the anti-cavitation performance is good.
