Semi-empirical model of a multi-diaphragm pump in an Organic Rankine Cycle (ORC) experimental unit

摘要

Organic Rankine Cycle (ORC) power systems represent an effective option to exploit low grade heat fluxes. Several papers have been published on ORCs systems, most of them dealing with the maximization of overall system performance and selection of the working fluid. Recently, the attention has moved also to system components with specific focus on the expander. Less attention was paid to the pump which, however, may contribute significantly to the system consumption, especially in small size systems.
