Parametric study of heat recovery from test engine cell applying the Rankine cycle with organic fluid

To evaluate the performance of an engine, it is needed to test engine experimentally. A Large amount of energy is wasted in the engine test cell. In the present work, in order to generate power from the waste heat, an Organic Rankine Cycle (ORC) is used. The waste heat is recovered in three separate heat exchangers (preheater, evaporator and superheater). These heat exchangers are separately designed, and the whole system is analyzed from the energy and exergy viewpoints. Finally, a parametric study is performed to investigate the effects of heat recovery temperature characteristics on important thermodynamic and heat transfer parameters. The results show that applying the ORC, recovers the heat losses equivalent to 8.85% of the engine power.
