results show a maximum expander isentropic efficiency of 72.4% and a relative cycle efficiency of 10.5% at an evaporation … to the expander causes a higher expander isentropic efficiency and higher cycle efficiency in the over-expansion mode …. However, in the under-expansion mode, the higher supply pressure results in a lower expander isentropic efficiency and …

this process, the isentropic efficiency of the expansion unit is considered to be unknown, and a theoretical approach for … the calculation of isentropic efficiency is presented. A number of influences are taken into account – dead volume … temperatures (333K–573K), engine speeds (5 Hz–30 Hz) and stroke volumes (0.1 L–50 L). The isentropic efficiency of water as working …
