ABSTRACT: This
study is devoted to the computational fluid dynamics (CFD) modeling of steady
laminar mixed convection flow and heat transfer in lid driven cavity (10 ≤ Re ≤ 1000). The
ratio of the height to the width of the cavity is ranged over H/L = 0.5 to 1.5. The
governing equations are solved using commercial finite volume package FLUENT to
visualize the nature of the flow and estimate the heat transfer inside the
cavity for different aspect ratio. The simulation results are presented in
terms of average Nusselt number of the hot wall, velocity profile, and
temperature contours. It was found that the average Nusselt number inside the
cavity is strongly governed by the aspect ratio as well as the Reynolds number.
A parametric study is conducted to demonstrate the effect of aspect ratio on
the flow and heat transfer characteristics. It is found that heat transfer enhancement
was obtained by decreasing the aspect ratio and/or increasing the Reynolds number.
