✦ Synopsis

The principle of lattice-Boltzmann techniques is recalled and some of the difficulties to simulate convective flows are discussed. It is then proposed to use a hybrid scheme with lattice-Boltzmann for fluid velocity variables and finite-difference for the temperature. Convergence studies are presented for particular cases. Some results for two and three-dimensional situations are given. Possible extensions of hybrid schemes are discussed.

In this paper, a finite difference-based lattice BGK model for thermal flows is proposed based on the double-distribution function approach. We applied this model to simulate natural convection heat transfer in a horizontal concentric annulus bounded by two stationary cylinders with different temper
