Summary

IRREVERSIBLE ENTROPY GENERATION FOR COMBINED FORCED CONVECTION HEAT AND MASS TRANSFER IN A TWO-DIMENSIONAL CHANNEL IS INVESTIGATED. THE HEAT AND MASS TRANSFER RATES ARE ASSUMED TO BE CONSTANT ON BOTH CHANNEL WALLS. FOR THE CASE OF LAMINAR FLOW, THE ENTROPY GENERATION IS OBTAINED AS A FUNCTION OF VELOCITY, TEMPERATURE, CONCENTRATION GRADIENTS AND THE PHYSICAL PROPERTIES OF THE FLUID. THE OPTIMUM PLATE SPACING IS DETERMINED, CONSIDERING THAT EITHER THE MASS FLOW RATE OR THE CHANNEL LENGTH ARE FIXED. FOR THE TURBULENT FLOW REGIME, A CONTROL VOLUME APPROACH THAT USES HEAT AND MASS TRANSFER CORRELATIONS IS DEVELOPED.
