Thermodynamic Design of Stirling Cycle Machines

When local, instantaneous departures from ideal reversible behaviour are evaluated in terms of the entropy generation rate, the differential equations describing the unsteady processes in the Stirling cycle machine give way to steady flow forms. A simple multiplication by T o gives immediately the local, instantaneous rate of loss of available work. The paper exploits this fact to obtain, from an ideal model of the flow processes, the indicated cycle work of the real (irreversible) cycle. The result is of the form: {( geometric parameters ), τγ, N RE , N PR , N F , … ( dimensionless groups in order of diminishing influence )} where τ, N RE ,
