The objective of the present study is to examine the characteristics of a fluid flow with rectangular fins in a lid driven square cavity. Lid-driven flow in a cavity has wide applications in microelectronic cooling devices, heat exchangers, solar energy collectors, building heating and ventilation systems, removal of air and water contamination from cavities, food heating and cooling devices, metal casting, galvanizing, metal coating etc. In view of this a numerical study has been carried out using COMSOL on mixed convection in a lid-driven square cavity with a rectangular fin. Flow and temperature fields were determined for different boundary conditions for vertical walls by considering both the top and the bottom walls as adiabatic. The fin is located on one of the stationary walls of the cavity. The simulated results were validated with the available literature for the case of a square cavity without fin. In the present investigation two different cases have been studied based on the location of the fin(s). The range of parameters considered in this study are: Rayleigh number Ra=103–105, dimensionless length (0.2 |
