In the present study, the effect of the inclination angle and geometric parameters of aluminum metal foam on heat transfer free convection is investigated numerically. Heat transfer and fluid flow in metal foam based on volume averaging theory and considering the thermal non-equilibrium condition for the energy equation, and the nonlinear Darcy-Brinkman-Forchheimer equation for the momentum equation is expressed in the porous region, microscopic equations in the pure fluid region and macroscopic equations in the porous region are solved. The finite element method has been used to solve numerical of momentum and energy equations in the porous region and pure fluid. In this study, influence of the inclination angle parameters of the metal foam heat sink, base temperature, and also geometric parameters of foam includes porosity, pore density, and foam height on the thermal performance of metal foam has been investigated. Numerical results show good agreement with the empirical results of others' works. Numerical results indicate that at the same temperature, the average Nusselt number of the metal foam heat sink in the horizontal position is 62.6% higher than the horizontal flat plate. Horizontal metal foam has the highest average Nusselt number compared to other angles; For metal foam with a pore density of 5ppi and a porosity of 0.92 in the horizontal position, the average Nusselt number is 22.3% higher than in the vertical position. Besides, in the upward horizontal position, the average Nusselt number is 29.5% higher than in the downward horizontal position.
