Abstract
Traditionally, Rankine cycles use water as working fluid and high temperature energy sources, above 370°C, mainly steam boilers. In Organic Rankine Cycle organic fluids are used with lower evaporation temperatures and pressures than water, allowing the use of heat from several sources with lower temperatures (between 60 and 250°C) for electricity generation. The main objective was use a model of radial inflow turbine coupled with a Organic Rankine cycle (ORC) model to analyze the influence of various parameters (flow coefficient, mass flow, angular speed and turbine inlet pressure) on the size of turbine and cycle net electric power output. The speed of turbine ω and mass flow rate m ̇ are the main parameters of influence in performance. Choice of working fluid can also significantly influence turbine and cycle performance
