Summary

THE PROBLEM OF MIXED CONVECTION FLOW ABOUT A VERTICAL, CYLINDRICAL FIN EMBEDDED IN A POROUS MEDIUM IS STUDIED ANALYTICALLY BASED ON THE CONJUGATE CONVECTION-CONDUCTION THEORY. A LOCAL NONSIMILARITY SOLUTION IS OBTAINED FOR THE CONVECTIVE FLOW IN THE POROUS MEDIUM. THE RESULTING SET OF ORDINARY DIFFERENTIAL EQUATIONS ARE COUPLED WITH THE ONE-DIMENSIONAL HEAT CONDUCTION EQUATION IN THE FIN THROUGH INTERFACIAL CONDITIONS. THE EFFECTS OF THE CONJUGATE CONVECTION-CONDUCTION PARAMETER, SURFACE CURVATURE AND THE MIXED CONVECTION PARAMETER ON THE FIN TEMPERATURE DISTRIBUTION, LOCAL HEAT TRANSFER COEFFICIENT, LOCAL HEAT FLUX, TOTAL HEAT TRANSFER AND FIN EFFICIENCY ARE ILLUSTRATED.
