ABSTRACT

The solidification process of nanofluid (water + copper nanoparticles) has been studied numerically in this paper. The horizontal walls of the cavity are insulated while inclined walls are kept at constant but different temperatures. The effects of nanoparticle dispersions (ϕ = 0%, 10% and 20%) and the temperature difference between hot and cold wall on the solidification of Cu-water nanofluid inside the cavity is investigated numerically. Enthalpy-porosity technique is used to trace the solid-liquid interface. It is illustrated that the suspended nanoparticles substantially increase the heat transfer rate which is further increased by the temperature difference.
