Abstarct: Today, the topic of energy is very important and vital.To reduce energy consumption, Focus on wasteful parts And its exploitation has been increased .Organic Rankine Cycle is One of the proper equipment for using low temperature source and Waste heat.The main advantage of the cycle is Using Organic Fluids. These fluids have a low boiling point and when exposed to a low temperature source they will evaporate. Generate more power and choosing the right fluid in this cycle is very important .In this research Cycle Power Generation will be evaluated. To achieve this goal, a Turbocharged turbine has been used. Firstly, this turbine has been modeled with specific geometry and then it is simulated using the numerical method and the Ansis Fluoent software. The modeling process involves selecting the appropriate computational grid, different boundary conditions and applying fluid settings in the software. The fluid used in the R245fa is selected according to the temperature and pressure conditions of the cycle. In the end, Numerical results are verified with laboratory results and after that, the turbine is computed under different input and output conditions. It can be seen that by increasing the inlet and outlet ratio and increasing the discharge, more output is obtained. This increase in power has been associated with increasing and decreasing the isotropic turbine output and for proper operation, there should be a correlation between the efficiency and the pressure ratio. Also, the increase in the pressure ratio increased the rotational speed but turbine torque did not have a clear trend and at first it is high and then decreases. In general, the purpose of this study is to model existing turbines And Deployment in the organic cycle of Rankine in order to benefit the vector of low temperature sources. Modeling by SIXDOF using sample Turbocharged turbine in the Rankine organic cycle is a new and unique method in this regard Wich enables the assessment of the power output of the cycle.
