Abstract

Natural convection in an inclined square enclosure heated with a uniform heat flux is investigated numerically in this study. Two-dimensional, steady, laminar flow is considered. Differential Quadrature (DQ) technique was used for numerical solutions. Two walls of enclosure are isothermal and partially heated with constant heat flux and other one is adiabatic. Grashof number is chosen between 103 - 106 and inclination angle is chosen as 0°≤ φ ≤120°. Length of heaters are ε=0.4. Results show that, quantitiy of heat transfer increases while Grashof number increases. Considering heated bottom and left walls, mean Nusselt number is higher at bottom wall for smaller values of inclination angle and higher at left wall for higher values of inclination angle. For 45° , average Nusselt number is equal for both walls.
