On the efficiency of a non-endoreversible Stirling cycle
In the present paper we make an analysis of the Stirling cycle from the point of view of finite time thermodynamics,assuming the existence of internal irreversibilities in an engine modeled by this cycle,and considering an ideal gas as working substance..We also seek for expressions for efficiency in both regimes: maximum power output and maximum ecological function.Appropriate variables are introduced so that the objective functions,namely power output,ecological function and efficiency can be functions of the reservoirs temperatures ratio and certain measurable parameters as a thermal conductance,the general constant of gases and the compression ratio of the cycle.Several results from the finite time thermodynamics literature are used,so that the developed methodology leads directly to appropriate expressions of the objective functions,simplifying the optimization process.
