RESUMO

The aim of the numerical study is to analyze the effect of partial heating/cooling and internal heat generation or absorption on mixed convection in a lid-driven cavity. Portions of the left and right walls are considered to be heating and cooling regions, respectively. Both (heating/cooling) regions are located at three different places on their respective walls. The remaining portions of the left and right walls and the horizontal walls of the cavity are taken to be adi-abatic. The results are shown graphically in the form of streamlines, isotherms, and velocity profiles to understand the influence of different locations of heating and cooling regions, different Richardson numbers, and internal heat generation or absorption parameters. It is observed that high heat transfer is found while locating the heating and cooling regions at Top-Top in the forced convection-dominated regime. It is also observed that heat transfer decreases in the presence of internal heat generation whereas it increases in the presence of internal heat absorption for all heating and cooling locations.
