MINIMIZATION OF ENTROPY PRODUCTION IN FULLY DEVELOPED MIXED THERMAL CONVECTION

ABSTRACT
The present study refers to a fully developed thermal mixed convection between two vertical and infinite walls having imposed constant temperatures and for a given flow rate (or pressure gradient). Viscous dissipation and entropy production are successively estimated and then used to find an optimum distance between the plates which minimizes the total entropy production in the flow field. Results indicated that the definition of a entropy criteria to use between different convection regimes is more difficult to apply than a dissipation criteria.
