In this paper we present an analysis of two Carnot-like endoreversible
thermal engines coupled through a thermal bypass. By means of the def
inition of a coupling parameter (alpha) we study some optimization cri
teria for this array of engines. We show that alpha works as a driving
parameter of the global power output and efficiency of the array. The
re exist alpha-values that maximize those quantities and we demonstrat
e that the coupled engines have performance advantages over the uncoup
led case.
