Summary

THE FRICTION FACTORS AND MASS TRANSFER COEFFICIENTS IN A TUBE WITH FINS OF E/D = 0.1, 0.2, 0.24 AND 0.3 ARE INVESTIGATED BOTH EXPERIMENTALLY AND THEORETICALLY IN THE WIDE RANGE OF REYNOLDS NUMBER UP TO 8000. THE FRICTION FACTOR DECREASED LINEARLY WITH REYNOLDS NUMBER UP TO REYNOLDS = 200 AND REMAINED NEARLY CONSTANT AT REYNOLDS HIGHER THAN 500 FOR ALL CASES OF E/D. THE PERFORATED FINS ARE PROVED TO BE EFFECTIVE BOTH IN REDUCING LOSS AND IN ENHANCING MASS TRANSFER.
