Entropy production of an arrangement in series of non-endoreversible thermal engines
One of the main objectives of thermodynamics the design and the analyze thermal engines considering that they produce the maximum amount of work,and a practical way to achieve this is to place these engines in series,because it has been found this type of power engines working in cycles produce energy availability greater than a simple engine.In this paper we study an arrangement series of irreversible heat engines working at maximum power output,taking into account its irreversibilities through a parameter R,called non-endoreversibility parameter,and which is given by the Clausius inequality.We obtain an expression for the efficiency of two irreversible coupled cycles.In addition we obtain the power output,entropy production and we construct the ecological function for two serially coupled engines.All our results are consistent with previous studies of the entropy production of a single engine.
