| Abstract: |
| In this paper,a new method for predicting the thermal conductivity of multi-phase ma-terial is proposed,and used to predict the thermal conductivity of porous material. Mean-while the effects of fraction,arrangement and shape of pores on overall thermal conductivityare discussed by utilizing materials having cylindrical pores,square pores and cracks.Com-pared with experimental data and theoretical model reported in the literature,it is found thatthe method proposed in this paper is successful and effective,and the results of the paper arein good agreement with those of experiment. |
