基于RE／CFD带分流叶片离心泵叶轮快速开发

针对带分流叶片离心泵叶轮结构复杂，传统水力设计需要设计者具有丰富的经验，开发周期长，成本高，很难适应产品快速开发需求的问题，采用逆向工程技术与计算流体力学（CFD）技术相结合的叶轮快速开发方法．利用ATOS流动式光学扫描仪对IS80—50—200型离心泵的带分流叶片叶轮进行数据测量，测量的点云导入CATIA中精确完成逆向建模，然后利用CFD软件Fluent对建立的模型进行额定工况下全流场的数值模拟来进行评价，对模拟结果中的相对速度，静压进行分析．结果表明，叶轮设计满足要求，此设计方法缩短了产品开发周期，降低了叶轮的设计成本．

Rapid development of centrifugal pump impeller with splitting vanes based on RE /CFD

The structure of centrifugal pump impellers with splitting vanes is complex and the traditional hydraulic design is depend on experience,so their development needs long cycle and high costs and it is difficult to adapt to fierce competition in the market.A method of rapid development impeller is introduced with combination of reverse engineering and CFD technology.The model studied is an IS80-50-200 pump.Under the ideological guidance in the reverse engineering,the date of impeller was measured by ATOS mobi...
