AB - The thermal property of closed-cell aluminum foam is studied numerically and  the effects of the distribution of the circular pore on the thermal property  are studied theoretically. When the convection and radiation are ignored, the  effects of porosity, cell size, and distribution forms of pore on the  apparent thermal conductivity are investigated. Moreover, the effects of air  in the pore on the thermal property are analyzed as well. Simulation results  show that apparent thermal conductivity linearly increases with the increase  of porosity, while the cell size and the distribution have negligible effects  on the thermal property. By comparison, thermal conductivity of air has  slight effect on thermal property of foamed aluminum in the context of small  size pore.
