Abstract

This paper presents the simulation of natural heat convection in an enclosure problem 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 effect of the Rayleigh number on the flow pattern in an enclosure filled with air heated by localized small source of heat at bottom wall was studied. The results explain the mechanism of natural convection rate increasing due to the Rayleigh number increasing. The comparison of the results was in excellent agreement with experimental results from literatures.
