Heat Transfer with Nanofluid: Experimental Investigation of Convective Heat Transfer of Al2O3-Water Nanofluid

The experimental apparatus is located at MNIT, Jaipur. To perform experiments in forced convective heat transfer at mass fluxes from 400 to 1000 kg/m2-s, heat fluxes from 0.1 to 0.5 MW/m2 and percent Al2O3 volume fraction varying from 0.25 to 1% At constant pressure 1 bar and environmental temperature for investigating the convective heat transfer characteristics of Al2O3/water nanofluid and to extend the available database and report information on heat transfer characteristics of Al2O3/water nanofluid in an annular test section with an inner heating surface. Forced flow conditions and particle migration is suggested to be an important mechanism. The results of the present investigation are summarized as follows: i. This study revealed that heat transfer increases with increase in mass flux at all given ranges of percent Al2O3/water nanofluid and heat fluxes. ii. The results of this experimental work shows that heat transfer increases with heat flux applied. iii. Heat transfer increases with addition of the Al2O3 nanoparticles in the base fluid.
