Abstract

The mixed convective flow of air in three-dimensional cubical lid-driven cavity flows are carried out numerically. The top lid assumed to be slide in its own plane at a constant speed. The horizontal walls are kept at an isothermal temperature in which the bottom wall has high temperature than the top. Numerical results are acquired for the control parameters arising in the system, namely, the Reynolds number (Re) in the range of 100–400 and the Richardson number (Ri) varying from 10−3 to 10. The fluid flow and heat transfer characteristics are visualized using the contours of streamlines, isotherms, vortex corelines with respect to different Ri and Re. The results are compared with the experimental/numerical results available in the literature and are found to be in good agreement.
