This work proposed a non-equilibrium mirror-reflection scheme to implement thermal boundary conditions for the two-distribution lattice Boltzmann method (TLBM). The study showed that the most popular non-equilibrium bounce-back scheme would become inadequate when the predictions of temperature gradi

This work proposed a unified approach to impose both nonslip and slip boundary conditions for the lattice Boltzmann method (LBM). By introducing the tangential momentum accommodation coefficient (TMAC), the present implementation can determine the change of the tangential momentum on the wall and th
We discuss three new implementation versions of diffuse reflection boundary conditions in a thermal lattice Boltzmann model. Their accuracy is investigated in the case of Couette flow by considering the slip regime. The best results are recovered with versions 2 and 3, which rely on outgoing fluxes
