Hybrid Lattice-Boltzmann simulation of convective flow in a channel with extended surfaces

Laminar convective flow in a channel with extended surfaces mounted at the bottom wall is investigated by using two methods. First, by the usual double-population SRT lattice Boltzmann method (LBM) and second by a hybrid scheme in which the flow is solved by single population LBM and the thermal fie...
