Exergy Analysis Of Regenerative Organic Rankine Cycle With Turbine Bleeding
This work presents an exergetical performance analysis of regenerative organic Rankine cycle (ORC) using
turbine bleeding based on the second law of thermodynamics for recovery of finite thermal energy. Effects of system
parameters such as turbine bleeding pressure and turbine bleeding fraction are theoretically investigated on the exergy
destructions (anergies) at various components of the system as well as the exergy and second-law efficiencies. Under the
conditions of the critical fraction of turbine bleeding, the simulation results show that the exergy efficiency decreases
monotonically with respect to the bleeding pressure, however, the second-law efficiency has a peak with respect to the turbine
