Abstract

This paper presents the simulation of natural heat convection in an enclosure with different aspects ratio using the lattice Boltzmann method. D2Q9 lattice model was coupled with the simplest D2Q4 lattice model to represent density and internal energy distribution function respectively. The effects of the Rayleigh number on the flow pattern at aspect ratio of 0.25, 0.5, 1.5, and 4 were studied. The enclosure is filled with air heated by small localized source of heat at bottom wall. The results explain the mechanism of natural convection rate increasing due to the Rayleigh number and aspect ratio changing. The comparison of the results was in excellent agreement with results from the literature.
