Abstract:
ABSTRACT Mixed convection in a double lid driven trapezoidal cavity with the presence of magnetic field has investigated numerically. The top and bottom walls are both adiabatic, the top wall moves with constant velocity to the left while the bottom wall moves with the same velocity of the top wall to the right. The left wall is maintained at constant hot temperature and the right wall is maintained at constant cold temperature.A finite volume method is used to solve the flow and energy equations. A collocated grid is utilized in the discretization of the governing equations; SIMPLE algorithm is used for coupling the velocity and pressure field. The range of Richardson number is (0.1≤ Ri ≤10), Hartmann number is (0≤ Ha ≤50), inclination angles of the side walls of the cavity are (0, 30o and 45o) and Prandtl number is 0.7. The results show that at mixed convection regime (Ri=1) and in the absences of magnetic field (Ha =0), the maximum heat transfer occurs for trapezoidal cavity at inclined wall angle (30o).
