AB - The nanofluids are widely used for heat transfer applications in the various  engineering applications. The nanoparticles dispersed uniformly in the base  fluid on proper mixing. In the present study, Al2O3 and CuO nanoparticles  were selected and the changes in the heat transfer coefficient were  investigated in the complete laminar and discrete points of transition fluid  flow through a copper tube with constant heat flux. The heat transfer  coefficient was investigated at different loading of Al2O3 and CuO  nanopowders ranging from 0.1% to 0.5% of volume concentration in each case  for the laminar and transition fluid flow zones, which is then compared with  the distilled water as a plain base fluid. It is found that the optimum  enhancement in heat transfer is observed at relatively lower volume fraction  of nanoparticles ranging between 0.2 to 0.3%.
