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

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
The lattice Boltzmann method is nowadays a common tool for solving computational fluid dynamics problems. One of the difficulties of this numerical approach is the treatment of the boundaries, because of the lack of physical intuition for the behavior of the density distribution functions close to t
