HAN Ya-fen;XIA Xin-lin;LIU Hai-dong;TAN He-ping;School of Energy Science and Engineering,Harbin Institute of Technology;  
In order to further investigate the heat conduction performance of aerogel nano-insulation material,this paper propose calculational model for solid and gas combined conduction in which the non-uniformity distribution of solid nanograin was taken into account.The thermal conductivity of aerogel nanograin was simulated using Lattice Boltzmann method.Based on the proposed structure model,the effects of density,side of structure and non-uniformity distribution of solid nanograin on the coupled thermal performance of aerogel were investigated.
