Large eddy simulation (LES) of turbulent heat transfer in isothermal porous media is performed by the lattice Boltzmann method (LBM) to discuss on modeling unknown terms of the double averaged energy equation. In this study, the regularized D3Q19 SRT model is applied to the thermal fields whilst the D3Q27 MRT model is applied to the flow fields. Using the LES data, a priori tests are carried out and it is confirmed that the sum of the volume averaged turbulent and dispersion heat fluxes can be reasonably modeled by gradient diffusion models.
