Abstract

In present work experimentation of shell and tube heat exchanger containing flow divider dimpled and without dimpled type baffles, at different mass flow rate (i.e. 4 (0.07kg/s), 6 (0.1kg/s), 8 (0.13kg/s), and 10 lpm (0.17kg/s)) has been conducted to determine pressure drop and heat transfer coefficient for shell side fluid. The more work had already been done on the heat exchanger performance. The heat exchanger performance enhanced by introducing new innovative baffles i.e. flow divider dimpled type baffles. In addition, the comparative study of shell and tube heat exchanger with flow divider dimpled and without dimpled type baffles were studied. Water is used for both shell and tubes as a working fluid. Based on the experimental result it has been establishing that the percentage increase in pressure drop and heat transfer coefficient for shell side is better in a heat exchanger with flow divider dimpled type baffles than without dimpled type baffles. The percentage increase in heat transfer coefficient and pressure drop for 4, 6, 8 and 10 lpm flow rates of shell side fluid was found to be 18%, 22%, 25%, and 33% and pressure drop 30%, 20%, 17% and 30% more in a heat exchanger with flow divider dimpled type baffles.
