PORE SCALE SIMULATION OF LAMINAR FLOWAND HEAT TRANSFER IN POROUS MEDIA USING THE LATTICE BOLTZMANN METHOD
ABSTRACT
In the present work, fluid flow and heat transfer in porous media were simulated at the pore scale using the lattice Boltzmann method. The method is based on random distribution of solid bars to generate the porous media in the desired region. To simulate the temperature field, a simplified thermal lattice BGK model with doubled population method was employed. The physical configuration is a parallel-plate channel with adiabatic walls filled with porous media. Comparing average Nusselt numbers in the present work with previous works, a reasonable agreement was observed.
