F121 Large eddy simulation of conjugate heat transfer in turbulent porous medium flows for discussion on turbulent and dispersion heat fluxes

Abstract

Large eddy simulation (LES) of conjugate heat transfer in a porous medium is performed by the lattice Boltzmann method to discuss on the unknown terms of the double averaged energy equation for modeling those terms. The D3Q19 SRT model with the regularization procedure is applied to the temperature fields in a cube matrix while the D3Q27 MRT model is applied to the velocity field in this study. The behaviors of turbulent and dispersion heat fluxes are studied by using LES data.
