LATTICE BOLTZMANN SIMULATION OF FLUID FLOW INDUCED BY THERMAL EFFECT IN HETEROGENEITY POROUS MEDIA

ABSTRACT
In this paper, a coupled lattice Boltzmann model is used to visually study fluid flow induced by thermal effect in heterogeneity porous media reconstructed by the quartet structure generation set. The fluid flow behavior inside porous media is presented and analyzed under different conditions. The simulation results indicate that the pore morphological properties of porous media and the Rayleigh number have noticeable impact on the velocity distribution and flow rate of fluid.
