Thermal matching performance of a geothermal ORC system using zeotropic working fluids
Yue, Chen; Han, Dong; Pu, Wenhao; He, Weifeng - In: Renewable Energy 80 (2015) C, pp. 746-754
The thermal matching performance analysis is conducted for a geothermal organic Rankine cycle system using zeotropic mixtures as working fluids. The constant isentropic efficiency is replaced by internal efficiency of an axial flow turbine with given size for each condition, and the zeotropic...
