Modelling and performance analysis for endoreversible Meletis-Georgiou cycle with non-linear relation between specific heat of working fluid and its temperature

Meletis-Georgiou (MG) vane rotor engine incorporates the exhaust gas recirculation process at the basis of Miller cycle, which produces a new cycle. An endoreversible MG cycle model is established using the finite time thermodynamic theory with considerations of heat transfer loss and the non-linear relation between specific heat of working fluid and its temperature. The analytical formulae of work output and efficiency are derived, and the cycle performance is analysed and optimised by detailed numerical examples. The effects of heat transfer loss, the non-linear relation between specific heat of working fluid and its temperature and design parameters on the cycle performance are discussed. The results obtained in this paper can provide some guidelines for the design of practical MG vane rotary engine cycle.
