Summary
This article reports on experimental work on the convective heat transfer of nanofluids, flowing through a copper tube in the laminar flow regime. The results showed considerable enhancement of convective heat transfer using the nanofluids. The enhancement was particularly significant in the entrance region, and was much higher than that solely due to the enhancement on thermal conduction. It was also shown that the classical Shah equation failed to predict the heat transfer behaviour of nanofluids. Possible reasons for the enhancement were discussed. Migration of nanoparticles, and the resulting disturbance of the boundary layer were proposed to be the main reasons.
