Note:
A general model for the study and optimization of two heat reservoirs thermal machine in presented. The mathematical model basically consists of the First and Second Laws of Thermodynamics applied to the cycle, and the heat transfer equations at the source and sink. The internal and external irreversibilities pf the cycle are considered by the entropy generation term. Several constraints imposed to the system composed by the engine and the two heat reservoirs allow to find the optimum operational conditions, as well as the limited variation ranges of the system parameters. Some results generated by the model when applied to thermal engines are presented.
