Abstract

Numerical simulation of natural convection in a nanofluids-filled partitioned square cavity is presented. Two independent solvers, an in-house LBE-BGK code and the commercially available software CFD-ACE, are used to achieve this goal. While the partitioning plates are generating heat at a uniform temperature, the vertical walls are isothermally cooled allowing for the removal of the internally generated heat with the horizontal walls being adiabatic. While the particle volume fraction is kept constant at 5%, the effective Rayleigh number, the length, and the orientation of the partition have been parametrically varied from 103–107, 0.25H–0.75H, and horizontal to vertical, respectively.
