Abstract : 3-D numerical simulation is performed for heat transfer and fluid flow characteristics of the tubes fitted with
twisted-tape inserts. The principle of heat transfer enhancement in the core flow of tube has been proposed to improve the
temperature uniformity and reduce flow resistance. Twisted tape widths are 13mm have been investigate at low Reynolds
number for different mass flow rates. The simulation results shows that the average overall heat transfer coefficient in circular
plain tubes are enhanced with twisted tape of widths by as much as 90% at a constant tube-side temperature and the friction
factor are enhanced. The twisted tape induced swirl flow heat transfer due to exponentially increasing heat inputs with various
exponential periods and twisted tape induced pressure drop were systematically measured.
