Belkacem Ould Said
Abstract
This research presents a numerical investigation of steady mixed convection in a two-dimensional vented porous enclosure incorporating an elliptical cylinder filled with a Cu/H2O nanoliquid. The flow dynamics of the nanoliquid are modeled using the Brinkman-Forchheimer approach. In this configuration, the upper and lower horizontal boundaries are maintained at hot (Th) and cold (Tc) temperatures, respectively, while the remaining walls are treated as adiabatic. The study systematically analyzes the influence of several dimensionless parameters: the Grashof number (Gr) spanning from 103 to 105, the Reynolds number (Re) ranging from 50 to 500, nanoparticle volume fractions between 0.1 and 0.6, the Hartman number (Ha) from 0 to 20, and various aspect ratios of the elliptical cylinder. The outcomes are illustrated through isotherm distributions, velocity streamlines, entropy generation rates, and the average Nusselt number. The variation of these parameters offers a pathway to effectively manipulate and enhance the heat transfer performance within the system, thereby providing valuable insights for engineering applications in thermal management.
