Abstract
Fluid flows and heat transfer processes inside cavities has been an active study field due to its geometry simplicity and capability of reaching complex regimes, presenting vortices and reincirculation. Since this problem has usual occurrence in engineering applications, many researchers have assessed square cavities using different numerical simulation approaches. In this context, Lattice-Boltzmann method (LBM) is one of the tools that has gained space in academy over the past two decades. In the present work, Lattice Boltzmann methods are used to solve mass, momentum and energy conservation equations by solving the evolution in time of two distribution functions. A square cavity with a length of size H = L and one inlet and outlet port, sized to W = 0:25H, is assessed in different hydrodynamic and thermal conditions. Natural convection is yet to be studied and added to the final paper. Preliminary results have shown good agreement with results available in literature.
