Numerical study of convective heat transfer and fluid flow through porous media

Lattice Boltzmann method (LBM) is applied to predict the phenomenon of natural convection in a generalised isotropic porous media model filled in a square geometry by introducing a force term to the evolution equation and porosity to the density equilibrium distribution function. The temperature fie...
