Abstract

The effects of nanoparticle dispersion \((\phi= 0, 0.025, 0.05)\) on solidification of different type of mixture of nanofluids namely, Cu-water, \(TiO_2\)-Water and \(Al_2O_3\)-Water nanofluid inside a vertical enclosure are investigated numerically for different Grashof number \(( Gr=10^4 ,10^5 ,10^6 )\). An enthalpy porosity technique is used to trace the solid and liquid interface. Comparisons with previously published works show the accuracy of the obtained results. A maximum of 16% decrease in solidification time for \(Gr=10^6\) in comparison with \(Gr=10^5\) was found with the Cu nanoparticles and 0.2% volume fraction. It was observed that dispersion of nanoparticles can be used to control the solidification time based on enhancing conduction heat transfer mechanism of solidification.
