Abstract An adsorption model for fluid flow, heat, and mass transfer of the adsorbent bed was established. Based on the single relaxation time lattice Boltzmann method, a dual-distributed lattice Boltzmann model of density and concentration was established to solve the fluid flow and mass transfer process in the surface area of the adsorbent bed. The adsorption and heat transfer process on the surface of the adsorbent bed was incorporated into the dual-distributed lattice Boltzmann model by the fourth-order Runge-Kutta finite difference method. The multiphysics fields under Poiseuille flow were simulated by the presented model, and the adsorption capacity and temperature distribution during the adsorption process were investigated.

Conjugate convective-conductive heat transfer in an enclosure is simulated. Internal heat and contaminant sources are included in the fluid flow domain, causing mass transfer within the cavity. The two-dimensional governing equations for natural heat and mass convection in the fluid phase and heat conduction in the solid phase are solved employing lattice Boltzmann method. The effects of Rayleigh number and buoyancy ratio variations on the fluid flow, heat and mass transfer characteristics are studied.
