AB - <p style="text-align: justify;">In this paper, a boundary condition-enforced IBM is introduced into the LBM
in order to satisfy the non-slip and temperature boundary conditions, and natural
convections in a concentric isothermal annulus between a square outer cylinder and a
circular inner cylinder are simulated. The obtained results show that the boundary
condition-enforced method gives a better solution for the flow field and the complicated
physics of the natural convections in the selected case is correctly captured. The
calculated average Nusselt numbers agree well with the previous studies.</p>
