【摘要】 Performance of a generalized Redlich-Kwong gas Stirling heat engine is investigated in which the multi-irreversibilities including thermal resista nee, rege nerative and heat leak losses are taken into accou
2、nt. General expressions for power output and efficiency of the Stirling heat en gine are derived, and effects of the non perfect regeneration and some important performance parameters such as the volume ratio and the temperature ratio are analyzed and discussed. Moreover; it is shown that the effici
