چکیده انگلیسی
Resolved large eddy simulations (LESs) of turbulent conjugate heat transfer in porous media are performed by the lattice Boltzmann method (LBM) for modelling turbulent and dispersion heat flux terms of the double-averaged energy equation. The considered porous structures are square rod arrays, staggered cube arrays and body centred cubic foam. In the LBM, the double-distribution function method which solves the distribution functions for the velocity and the internal energy is used. For the velocity and thermal fields, the D3Q27 multiple-relaxation-time method and the regularized D3Q19 single-relaxation-time method are applied, respectively. A priori tests using the LES data suggest that the trends of the sum of the dispersion and volume-averaged turbulent heat fluxes can be well captured by the second order gradient diffusion model.
