In this paper, natural convection heat transfer from heated plate positioned in square cavity vertically and horizontally was studied. Thermal BGK lattice Boltzmann numerical scheme was applied. The simulation was launched for different aspect ratio A=0.4 and 0.6 at Grasshof numbers and . Air was chosen as working fluid (Pr=0.71). Good arrangement was obtained between the present work and pervious approach using finite volume method. It is found that convection upper side of plate is increase as Grasshof number is increased.

“…In the past few years, many researchers have developed new methods to study the fluid flow phenomenon in a cavity [3][4][5][6][7]. Among the proposed methods in the literature, the lattice Boltzmann method (LBM) has received the biggest attention and has developed to be an alternative numerical tool for simulation this kind of fluid flow problems [8]. McNamara and Zanetti [9] firstly demonstrated the capabilities of the LBM.…”

“…After detailed survey on available literature, many researchers have developed new methods to study the fluid flow phenomenon in a cavity. Among the proposed methods in the literature, the lattice Boltzmann method (LBM) has received the biggest attention and has developed to be an alternative numerical tool for simulation this kind of fluid flow problems [8]. Numerical model for this study is to couple the lattice Boltzman formulation with the Brinkman-Forcheimer equation to solve fluid flow through porous media.…”

Investigation of vortex shedding behind a porous square cylinder using lattice Boltzmann method Phys. Fluids 22, 053605 (2010); Abstract. This work presents a simulation of incompressible viscous flow within a two-dimensional square cavity filled with porous medium. This study aims to analyze the flow in a lid-driven cavity flow with different Reynolds number and porosity values. The Brinkmann-Forcheimer equation was coupled with Lattice Boltzmann formulation to predict the velocity field in the system. The Lattice Boltzmann Method (LBM) which is known as discrete lattice kinetic is chosen to provide solution for Navier-stokes equations. A specific two-dimensional nine-velocity square lattice model (D2Q9 Model) was used in the simulation. It is found that the LBM is an efficient method to reproduce the dynamics of cavity flow and found to reproduce results comparable to previous work.
