ABSTRACT:
The study of local stability of thermal engines modeled as an
endoreversible Curzon and Ahlborn cycle is shown. It is assumed a non-linear
heat transfer for heat fluxes in the system (engine + environments). A semisum
of two expressions of the efficiency found in the literature of finite time thermodynamics
for the maximum power output regime is considered in order to make the
analysis. Expression of variables for local stability and power output is found
even graphic results for important parameters in the analysis of stability, and
a phase plane portrait is shown.
