Summary

HEAT TRANSFER AND PRESSURE DROP EXPERIMENTS WERE PERFORMED FOR CROSSFLOW TUBE BANKS IN WHICH THE INDIVIDUAL TUBES WERE EQUIPPED WITH LONGITUDINAL FINS. THE INVESTIGATED PARAMETERS INCLUDED THE PLACEMENT OF THE FINS, THE FIN TIP SHAPE, AND THE FIN THICKNESS. FOR EACH BANK GEOMETRY, THE REYNOLDS NUMBER WAS VARIED BY AN ORDER OF MAGNITUDE. A HIGH DEGREE OF HEAT TRANSFER ENHANCEMENT CAN BE OBTAINED BY FINNING. THE ENHANCEMENTS FOR THE VARIOUS TUBE BANK GEOMETRIES WERE COMPARED AT FIXED PUMPING POWER, FIXED PRESSURE DROP, AND FIXED MASS FLOW. FINNING WAS FOUND TO BE ESPECIALLY ADVANTAGEOUS WHEN THE COMPARISON IS MADE AT FIXED PRESSURE DROP.
