摘要
采用CFD方法对某型轴流喷水推进器的基本性能进行测算。该型喷水推进器原用于一款小型高速摩托艇,具有工作转数高、推力大的特点。运用fluent软件以及RNGk-ε湍流模型、SIMPLEC算法、多重参考坐标系(MRF)对其进行数值计算,研究喷水推进器的设计流量、扬程、转矩、功率等性能参数,得到流场的速度和压力分布,为优化推进器的性能提供依据。
By the means of CFD,the basic performance of a type of water-jet is studied. This water-jet was used in a small high speed watercraft with the features of high revolution and strong thrust. Making use of Fluent software,RNG k-ε turbulence model,SIMPLEC arithmetic and multiple reference coordinate system,the performance parameters of design flow,head of delivery,torque and power of the pump are calculated numerically,obtaining the velocity and pressure distribution of the flow field. It is helpful for the performance optimization of the impellers.
