摘要
简要介绍了计算流体力学(CFD)技术的发展与数值方法。列举CFD通用分析软件应用于汽轮机通流级分析的几个典型算例。分析结果表明,应用先进的计算流体力学(CFD)技术进行汽轮机的通流设计,可有效提高设计机组的通流级效率和设计质量。CFD技术在汽轮机通流设计中的应用缩短了产品开发周期,节约了开发成本。
In this paper,the development and the numerical method of CFD technique are introduced. A few typical exampies using the general CFD analysis software to design the flow-path of steam turbine are enumerated. Result of flow-field analysis shows that the application is very efficient to improve the efficiency of steam turbine stages and quantity of design. The product development period has been shortened and the development cost has been economized by applying CFD technique.
