TL;DR: In this paper, natural convection in air-filled 2D square enclosure heated with a constant source from below and cooled from above is studied numerically for a variety of thermal boundary conditions at the top and sidewalls Simulations are performed for two kinds of lengths of the heated source, i.e., small and large sources corresponding to 20% and 80% of the total length of the bottom wall, respectively.

TL;DR: Ouertatani et al. as discussed by the authors used a numerical approach based on the finite volume method and a full multigrid acceleration, applied to the classical Rayleigh Benard convection problem.

TL;DR: In this paper, the authors used the finite volume method and a full multigrid acceleration to study the intricate three-dimensional flow structures and the companion heat transfer rates in double lid-driven cubic cavity heated from the top and cooled from below.

TL;DR: In this paper, an accelerated full-multigrid scheme for an efficient modeling of time-dependent buoyancy-driven flows is presented, where an acceleration parameter, Γ, is implemented in the classical full multigrid procedure in order to improve the convergence.

TL;DR: In this article, a numerical study of natural convection in a square enclosure with non-uniform temperature distribution maintained at the bottom wall and filled with nanofluids is carried out using different types of nanoparticles.
