Abstract


Objective: The present study was made to investigate the enhancement in the heat transfer characteristics of CuO water base nanofluids by inserting the baffles in the annulus of the double pipe heat exchanger. Statistical Analysis: The experimentation was carried out with distilled water and copper oxide water base nanofluids at 0.1% and 0.2% volume concentration. The effect on heat transfer coefficient and Nusselt number is determined in this experiment at various temperatures. Findings: It has been observed that in comparison to the distilled water, copper oxide nanofluids with baffles shows more heat transfer enhancement. The result showed that the Nusselt number increased by 8% without introducing baffles and nanofluids and 10-12% enhancement was observed with baffles and nanofluids. The enhancement of 22-25 % has been observed in the heat transfer coefficient at 0.1% volume concentration and 25-30 % of enhancement 0.2% volume concentration. Applications: In automobile radiators, cooling towers, air preheaters, refrigeration, air conditioning, condensers etc double pipe heat exchanger with baffles inserts can be easily implemented.
