Study of the Reconstruction of Fractal Structure of Closed-cell Aluminum Foam and its Thermal Conductivity

Based on the characteristics of the internal structure of closed-cell aluminum foam, this paper attempts to illustrate the process of reconstructing the internal structures of closed-cell aluminum foam in Monte-Carlo method and the fractal characteristics of the reconstructed model. Furthermore, Binary Array Method is proposed by analyzing the reconstructed model and the thermal conductivity model of closed-cell aluminum foam is established. At the same time, the thermal conductivity of the foam materials with different porosity is calculated by Binary Array Method, and the calculated value coincides with the experimental results in the reference, which proves the correctness of these methods.
