Abstract: This study presents a numerical investigation of laminar natural convection heat transfer in an inclined enclosure, differentially heated, with inclined partitions attached to its hot wall. The top and bottom walls of the cavity are insulated. Numerical solutions are obtained by using the hybrid lattice-Boltzmann method finite-difference. Effects of partition length, partition inclination angle, partitions number and aspect ratio cavity are studied for Prandtl number 0.71 and cavity inclination angles of 45∘ and 90∘. Rayleigh numbers considered are 5×105 for a square cavity and 104 for a cavity with an aspect ratio equal to 6. Results are reported in terms of isotherms, streamlines, local and average Nusselt numbers.
