ShareSummary
THE EFFECT OF EQUIPPING THE TUBES WITH LONGITUDINAL FINS ON THE PRESSURE DROP AND HEAT TRANSFER IS STUDIED. THE GOVERNING EQUATIONS FOR FLUID FLOW AND HEAT TRANSFER ARE NUMERICALLY SOLVED,WITH THE ASSUMPTION OF PERIODIC, FULLY DEVELOPED FLO THE TUBES ARE MAINTAINED AT A CONSTANT TEMPERATURE, AND THE CALCULATIONS ARE CARRIED OUT FOR LAMINAR FLOW AND FOR A LARGE RANGE OF REYNOLDS AND PRANDTL NUMBERS. THE RESULTS FOR THE UNFINNED TUBE CASE AGREE WELL WITH THE EXPERIMENTAL MEASUREMENTS. REPRESENTATIVE RESULTS FOR THE CASE OF THE FINNED TUBES INDICATE A DECREASE IN THE HEAT TRANSFER RATE, AND SMALL CHANGES IN THE PRESSURE DROP, AS A RESULT OF FINNING.
