Abstract

In this paper, a general expression is obtained for the entropy generation for combined convective heat and mass transfer in external flows. This expression accounts for irreversibilities due to the presence of heat transfer across a finite temperature difference, mass transfer across a finite difference in the chemical potential of a species, and flow friction. Minimizing the entropy generation in heat- and fluid-flow devices is a valuable criterion for optimum design. The present paper shows that the same philosophy can be used when in addition to heat transfer and fluid flow irreversibilities, mass transfer irreversibilities exist in the thermal system of interest. The general expression for entropy generation is applied to two fundamental problems of forced convection heat and mass transfer, namely, laminar and turbulent boundary layer forced convection from a flat plate and from a cylinder in crossflow. After minimizing the entropy generation, useful conclusions are drawn that are representative of the second law viewpoint for the definition of the optimum operating conditions for the specified applications.
