| description | In order to obtain the gas heat conduction of aerogel materials, this paper applied lattice boltzmann method (LBM) to establish a microcosmic model D3Q15. Lattice Boltzmann method (LBM) was used to simulate the temperature distribution and had the advantage of simplifying calculation at the nano scale. Gas heat conduction would be effected by the size and boundary condition under nano-scale conditions. In this paper it can be concluded that the temperature jump under mirror rebound and diffuse reflection boundary was obvious as the value of t increasing from 8*10−12 to 4*10−9 and the mirror rebound boundary scattering increased drastically than diffuse reflection. the temperature jump would stay stable when the time arrived 4*10−9. As to diffuse reflection boundary, the effective thermal conductivity tended to decrease dramaticlly as rb growing up. |
