Summary

MOST PREVIOUS WORK ON FIN PERFORMANCE HAS ASSUMED PERFECT CONTACT BETWEEN FIN AND PRIME SURFACE. THIS PAPER INVESTIGATES THE ACCURACY OF THIS FOR LONGITUDINAL FINS ON A PLANE SURFACE. ASSUMPTIONS MADE ARE THAT CONTACT IS EQUALLY DISTRIBUTED ABOUT THE CENTRE LINE OF THE FIN AND THAT NO CONVECTION IS POSSIBLE IN THE SMALL SPACE AT NON-CONTACTING AREAS. THE RESULTS INDICATE THAT THERE IS VERY LITTLE DROP IN OVERALL HEAT TRANSFER FOR CASES WHERE CONTACT IS BETTER THAN 10% OF THE MAXIMUM AND THAT POOR CONTACT CAN THEREFORE BE NEGLECTED IN MOST PRACTICAL CASES. D.W.H.
