Design and Simulation of Power Turbine for Micro Organic Rankine Cycle Thermoelectric System

Abstract

A miniature power turbine for the micro Organic Rankine Cycle (ORC) system is designed in this paper. In order to judge the aerodynamic performance of the power turbine system, the PROE software is used to model the main components of the turbine, and the TURBO tool of ANSYS GAMBIT is used to carry out the finite element meshing, and the thermal performance of refrigerant is written by UDF of FLUENT 6.3 software, then aerodynamic simulation is carried by FLUENT 6.3 software. The results show that the designed aerodynamic performance is good, and the kinetic energy efficiency is 73.86% under the stable condition.
