AB - In the present study, a double-population thermal lattice Boltzmann was  applied to solve phase change problem with natural convection in an eccentric  annulus. The simulation of melting process from a concentrically and  eccentrically placed inner hot cylinder inside an outer cold cylinder with  Prandtl number of 6.2, Stefan number of 1 and Rayleigh number of 105 was  carried out quantitatively. It was found that the position of the inner  cylinder inside the outer cylinder significantly influence the flow patterns  including the size and shape of two formed vortexes. It is also observed that  the maximum of liquid fractions occurs where the inner cylinder is mounted at  the bottom of outer cylinder.
