【摘要】 本文利用CFD通用软件-FLUENT6.1.22模拟了椭圆型平进口喷水推进器进水管内的三维粘性流场;在考虑边界层和不考虑边界层两种情况下,研究了IVR(船速与进水速比)对流场速度分布和压力分布的影响,分析不同IVR下产生空化现象的可能性。在流场的模拟过程中、提供可视化流动细节供设计参考,为喷水推进进水管的设计及进水口的形状优化提供依据。更多还原

【Abstract】 On the basis of CFD Theory,this paper simulates fluid flow in the elliptic flash intakes of waterjet propulsion by the current software(FLUENT6.1.22). Analysis the influence of boundary layer on flow and pressure distribution as well as the probability of causing cavitation at different IVR.Providing reference for inlet shape design and optimism by the result of flow visualisation.更多还原
