Kinetic theory analysis of thermal conductivity in granular material flows

研究成果: 雜誌貢獻會議論文同行評審


The effective thermal conductivity is developed by employing the dense-gas kinetic theory. The free path used in the theory varies with the particle velocity. The analytical results can be used for the whole range of the product of Biot number and Fourier number provided that the Biot number is less than 0.1. For the very small Biot-Fourier numbers, the conductivities are found to increase with the particle diameters and the square root of granular temperatures. For the limit of very large Biot-Fourier numbers, the two effective-thermal conductivities are found to be linearly proportional to the granular temperature.
