摘要：

The transport properties of convection rolls in a two-dimensional vibrating granular bed are investigated in this paper. The image processing technology and particle tracking method were employed to measure the fluctuation velocities and the self-diffusion coefficients. The fluctuation velocities, granular temperatures, and self-diffusion coefficients were anisotropic with the greater components in the vertical direction of the two-dimensional vibrating granular bed and increased with the increase of the vibrational acceleration and the vibrational velocity. The influence of the vibration conditions on these transport properties is discussed in the paper. (C) 2004 Elsevier B.V. All rights reserved.
