Abstract

The present work shows the result obtained from experimental investigation of heat transfer enhancement in circular tube inserted with twisted tape by forced convection in horizontal tube at different velocity and different set of twisted tape, air as working fluid. The experiments were conducted on circular tube inserted with different sets of twisted tapes of diameter 33mm and length 400mm are inserted in the entire length of the tube in the orthogonal direction. Theoretical and experimental heat transfer coefficient are calculated, the heat transfer coefficient, nusselt number, pressure drop and friction factor data obtained is compared with the data obtained from a plain circular tube. The twist ratio is (12, 6, 4).
