Turbulent Convective Heat Transfer γ-Al2O3 / Water Nanofluid through Double Pipe Heat Exchanger

An experimental investigation was carried out to obtain the convective heat transfer coefficient and Nusselt number of γ -Al2O3 / water nanofluid through double pipe heat exchanger. The effects of different parameters such as Reynolds number, Graetz number and nanoparticle concentrations on Nusselt number and convective heat transfer coefficients were investigated. All the experimental data showed an increase in heat transfer coefficient and Nusselt number of nanofluid in comparison with pure distilled water.
