摘要
简要介绍了水轮机、水泵水轮机、离心泵反转液力透平设计方法,针对液力透平实际工作条件和结构特点,提出依据介质流量、可利用水头、转速等工况条件确定液力透平特征参数,进行转轮、蜗壳、导叶或导流段等过流部件的一维设计的方法;在二维造型和局部优化、三维流场数值仿真和结构、性能优化基础上,形成液力透平的直接正向设计方法。
In this article, the design methods for water turbine, water pump-turbine and centrifugal-pump-turbine were introduced. With respect to practical working condition and structural features of hydraulic turbine and based on parameters of flow volume, useful water head and rotary speed, one directional design method for impeller, turbo shell, blade and guide segment was presented. Then on the basis of 2D modelling and local optimization, numerical simulation of 3D flow field and structural and characteristics optimization, direct and forward design method for hydraulic turbine was proposed.
