摘要

为了设计浸没式喷水推进泵

以国外某喷水推进混流泵为对象建立了浸没式喷射模型

运用计算流体力学(CFD)瞬态模拟方法研究了2种转速时浸没式喷射对喷水推进泵水力性能的影响。研究表明

无论是低转速还是设计转速

浸没式喷射时喷水推进泵的扬程、轴功率、效率变化都小于1%

且叶片的空化无明显变化。由此

运用三元设计方法设计了一型适用于常规尾板式喷水推进的喷水推进泵

即按常规尾板式喷水推进的“船-泵-机”匹配方法选定喷水推进泵的设计参数

按基于环量的三元方法进行喷泵的水力设计

喷泵为6片叶片、9片导叶。最后

运用计算流体力学方法对实尺浸没式喷水推进器与船体的组合结构进行了数值模拟

结果表明

在设计航速时

该喷水推进泵完全浸没在水中工作的水力性能变化很小

进而得出浸没式喷水推进泵可以按照常规尾板式喷水推进泵的设计方法进行设计的结论。

Abstract

To design submerged waterjet pump

a submerged model for a mixed-flow pump is established and the performances at different rotating speeds are analyzed with CFD transient method. The head

power and efficiency of the pump change less than 1% at either low or designed rotating speed

and the impeller cavitation almost appears constantly. A traditional waterjet pump is chosen by matching ship

waterjet and engine

and designed with three-dimensional strategy according to the velocity circulation

the impeller vanes are taken as six and the guide vanes as nine. A full-scale ship propelled by the waterjet pump is investigated

and it is found that at the designed speed

the performances of the waterjet pump working under water change slightly

so submerged waterjet pump can be designed following the traditional waterjet pump designing method.
