Abstract

Natural convection heat transfer in a porous trapezoidal cavity with an inside horizontal thin plate heater has been investigated numerically. The sloping walls of the trapezoid are maintained at constant temperature T c, while the top and bottom walls are insulated. A thin plate heater with temperature Th (Th>Tc) is located inside the porous trapezoidal cavity. The governing equations are discretized using a finite difference method. The study was performed for different Rayleigh number ranging from 10 to 104 with different inclination angles of the sloping wall. The results indicate that the heat transfer performance decreases by decreasing the angle of the sloping wall.
