Laminar Natural Convection Over A Heated Cylinder in A Cubic – A Lattice Boltzmann Study

Abstract
In the present study, the thermal lattice Boltzmann scheme is used for simulating the natural convection in cubical enclosure with different inner cylinder positions at Rayleigh numbers of 104- 106 and a Prandtl number of 0.7. The location of the inner cylinder is changed vertically along the centerline of the enclosure. The transient state and steady state results are investigated and analyzed. The effects of the boundary wall on heat transfer and fluid flow in the enclosure depend on both the position of the cylinder and the Rayleigh number. Detailed discussion for the streamline, isotherms, and Nusselt number distribution is presented in this paper. Lattice Boltzmann method, Cubical enclosure, Inner cylinder, Natural convection
