摘要

为改进某高速摩托艇喷水推进器推进性能，运用计算流体力学方法通过求解雷诺时均的控制方程，计算喷水推进泵和“喷水推进泵+进水流道+格栅+船体”的流场特性.利用CFX软件进行后处理，分析喷水推进泵和“喷水推进泵+流道+格栅+船体”的流场特性，针对其流道内存在涡流及推进效率偏低现象，提出对流道几何进行优化的处理方案.通过对进水流道进行优化设计，喷水推进效率提高6%.

Abstract

Computational fluid dynamics is applied to analyze the propulsive performance of a certain motorboat propelled by waterjet. The flow fields of a waterjet pump and a “waterjet+duct+grid+hull” system are calculated by Reynoldsaveraged NavierStokes (RANS) equations. Studying the behaviors of the flow fields with CFX postprocessing technology, some shortages are identified that eddy existes at the root of inducer blade and the back of the duct, the efficiency of propulsion also seems lower. For these problems, an optimized geometry of the duct is proposed to improve the propulsive efficiency of the waterjet propulsion system . Results show that an optimized duct can increase the propulsive efficiency by 6%.

Key words： motorboat; water jet propeller; performance analysis; computational fluid dynamics（CFD）
