Abstract

The present paper deals with a numerical study of natural convection in a square cavity filled with a nanofluid. The left and right vertical walls of the cavity are maintained at a local temperature Th (heat source) and a local cold temperature TC, respectively. Horizontal walls are assumed to be adiabatic. The governing equations are discretized by using the finite volume method and solved by the SIMPLER algorithm. Our computer fortran code is validated through comparison with numerical results found in the literature. Results are presented in terms of streamlines, isotherms, local and average Nusselt numbers for the Rayleigh number (103Ra ≤ 106), solid volume fraction of nanoparticles (0 ≤ Ø ≤ 0.10), type of nanofluids (Cu, Ag, Al2O3 and TiO2), and dimensionless length of the heat source (0.50 ≤ B ≤ 1).
