Abstract

A numerical study is performed to analyze the mixed convection flow and heat transfer in a lid-driven cavity with sinusoidal wavy bottom surface. The cavity vertical walls are insulated while the wavy bottom surface is maintained at a uniform temperature higher than the top lid. A finite volume method is used to solve numerically the non-dimensional governing equations. The tests were carried out for various inclination angles ranging to 0° from 180° and number of undulation varied from 4 to 6, while the Prandtl number was kept constant Pr = 0.71. Three geometrical configurations were used namely four, five and six. The distributions of streamlines and isotherms, and the variations of local and average Nusselt numbers with the inclination angle are presented. The results of this investigation illustrate that the average Nusselt number at the heated surface increases with an increase of the number of undulations as well as the angle of inclination.
