500kW有机工质向心透平气动设计

Aerodynamic Design of Radial Turbine for 500kW ORC System

对500kW等级ORC向心透平进行气动设计,利用NREC-Rital模块进行一维热力计算,并进行动静叶造型设计。利用Numeca软件进行向心透平气动性能校核,仿真结果表明:设计的向心透平设计点气动性能优良,满足设计要求。

In this paper a radial turbine for 500kW ORC system is designed with the tool of NREC-Rital.After 3D modelling of the stator and rotor,numerical simulation is carried out using commercial CFD code Numeca.The simulation results indicate that the turbine designed in this paper has excellent aerodynamic performance and meets the design requirement.
