Abstract: Convective heat transfer characteristics within a heat exchanger with twisted tapes of different cuts and materials have been investigated experimentally. Effect of twisted tape of different cuts (square, circular and triangular) inside the inner tube of single unit on heat transfer and friction factor for heating of water for Reynolds number range 500-3000 was studied experimentally. The results obtained from the twisted inserts of GI, Al and Cu materials are compared and the experimental results reveal that the among the three different materials of inserts, Copper inserts performs better and too with square cuts.
