The heat and mass transfer through porous building envelope has an important impact on the hydrothermal performance of building enclosure, energy consumption and indoor environment. This article proposes a lattice Boltzmann method to simulate the double-diffusive mixed convection, fluid-solid conjugate heat transfer and adsorption process by porous media in an enclosure simultaneously. A double distribution lattice-Boltzmann model is established to implement heat transfer between fluid and solid and the adsorption behavior of porous media. The numerical investigations are performed at the pore scale with the considerations of interparticle, interfacial, and intraparticle heat and mass transfer characteristics. At Richardson numberRi=1.0, Lewis numberLe=10, Buoyancy ratioBr=1.0, Prandtl numberPr=0.7, Grashof numberGr=104and porosityɛ=0.79, investigating absorption behaviour and time consumption concluded that increasing particle size led to a moderating adsorption rate and more time consumed to approach the saturation adsorption. Streamlines, isotherms, isoconcentrations, and the average Nusselt numberNuavand Sherwood numberShavalso reported in detail.
