Combined Convection Flow through Inclined Square Enclosure with a Sliding Corrugated Hot Top Surface

Abstract

This research project was a study of combined convection flow through inclined square enclosure with a sliding corrugated hot top surface. The hot isothermal top wall was corrugated with three undulations and the wave amplitude was 0.1 and was sliding at constant velocity. The bottom wall was fixed and kept at isothermal cold temperature. The other side walls were thermally insulated. The inclination angle was kept constant at 100 with the enclosure filled with water as a working fluid. The velocity profile and temperature distribution was obtained using MATLAB. The partial differential equations governing water velocity and temperature distribution were solved numerically using Finite Difference Method and the result were discussed and presented in tables and graphs. The effects of Richardson number and Reynolds number on velocity flow and temperature distribution in the enclosure were analyzed with Prandtl number kept constant.
