Turbulent convective heat transfer of nanofluids through a square channel
This paper reports the results of experimental investigation on the heat transfer performance of Al2O3/H2O and TiO2/H2O nanofluids through square channel with constant wall temperature boundary condition. The flow regime through channel is turbulent. The nanofluids used in this research are Al2O3/H2O and TiO2/H2O with different nanoparticle concentrations. Based on the results of the present investigation, for specific Peclet number, convective heat transfer coefficient and Nusselt number of nanofluids are higher than those of distilled water. The enhancement increases with increasing nanoparticle concentration. The results also reveal that the convective heat transfer coefficient for Al2O3/H2O nanofluid is relatively the same as that of TiO2/H2O nanofluid.
