Abstract

In this work, a steady mixed convection in a two-dimensional enclosure filled viananoliquid Cu/H2O through a porous medium was numerically analyzed. The nanoliquid flow is designated utilizing the Brinkman-Forchheimer model. The upper and the bottom horizontal walls are considered to be hot (Th) and cold temperature (Tc), respectively, whereas the other walls are thermally insulated. The impact of various dimensionless terms such as the Grashof number (Gr) in the ranges (0.01–20), the Reynolds number (Re) in the ranges (50–500), the Hartman number (Ha) in the ranges (0–20), and three different location cases (0.25, 0.5, and 0.75) are carefully analyzed. The obtained outcomes are established in the form of isotherms, streamlines, and the average Nusselt number. It has been found that heat transport increases significantly through rising Reynolds number (Re). For the location cases L = 0.25, Re = 50, and Gr = 10⁵, the heat transfer is maximum.
