Double-Difffusive Natural Convection of TiO2-Water Nanofluid in a Square Cavity

Abstract

Natural convection heat and mass transfer in a square cavity is numerically studied in the present paper. The cavity is filled with a water-based nanofluid containing TiO2 nanoparticles. The governing equations are solved numerically using the finite volume method. The velocity-pressure coupling is achieved using the SIMPLER algorithm. This study focuses on the effect of some parameters, namely, the Rayleigh number and the nanoparticles volume fraction on the flow pattern as well as on heat and mass transfer.
