Study of double-diffusive natural convection and radiation in an inclined cavity using lattice Boltzmann method

► A combined double diffusive convection and volumetric radiation was investigated. ► A hybrid scheme with MRT-Lattice Boltzmann and finite difference method is used. ► The radiative source term is evaluated by the discrete ordinates method (DOM). ► The iso-lines are inclined in cavity core and the flow is stabilized in aiding case. ► The multicellular flows are promoted for the opposite flow case.
