Thermal properties of closed-cell aluminum foam with circular pores
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 p...

description |
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. |
