Experimental studies of heat transfer of TiO2/CuO water based nanofluid in a double pipe heat exchanger has been performed by varying flow rate and concentration of nanoparticles from 1 LPM to 4 LPM and 0.1% to 0.3% by volume respectively at ambient temperature. The results predicts that CuO act as a better nanoparticle in comparison to TiO2. Various correlations were fitted to verify the suitability of the best fit and revealed better agreement with Duangthongsuk and Wongwises correlations.
