Numerical simulations of effective thermal conductivity in aluminum foam sandwich panel

In this work, the effective thermal conductivities of aluminum foam sandwich panels with the porosity range from 40% to 60% were studied by simulation method. The influence of porosity and pore size on the effective thermal conductivities was analyzed, and their influence mechanism was studied. In addition, simulation results were verified by theoretical formula. This further proves the feasibility of simulation method for research on the effective thermal conductivity of aluminum foam sandwich panels. The results confirmed that the porosity and pore size of aluminum foam sandwich panel had great impact upon its effective thermal conductivity
