Analysis on Heat Transfer Performance of Porous Aluminum Alloy Based on Ansys Workbench
Using porous aluminum alloy as research object, a connecting groove foam structure and mathematical model was established. Finite element analysis method was adopted to simulate the thermal properties by using Steady-State Thermal module in Ansys workbench software. The results show that the porous aluminum alloy exhibit gradient distribution from the front of the heating surface to the undersurface. The more near the center of the surface, the slower the temperature decreases, but close to the junction of surface to surface, the temperature decreases faster, where the maximum and minimum temperature is 300 ℃ and 263.57 ℃, respectively. The heat flux of the porous aluminum alloy along the temperature gradient direction is nonlinear; the maximum and minimum heat flux is 1.24 ×105W/m2and 22.12 W/m2.
