摘要

讨论了颗粒介质在粗溜槽上快速重力流过程中颗粒温度的研究结果。颗粒温度由颗粒相互位移的几种形式的动能决定。分析了溜槽角度对颗粒温度各组分值比的影响。考虑了颗粒的波动、剪切和横向相互位移引起的颗粒温度分量。

Quasithermal Effects During Rapid Gravity Flow of a Granular Medium
The investigation results of granular temperature during rapid gravity flow of granular medium on a rough chute are discussed. The granular temperature is determined as the kinetic energy of several forms of mutual displacements of particles. The influence of the chute angle on the value ratio of different components of granular temperature is analyzed. The components of granular temperature induced by fluctuation, shear and transversal mutual displacements of particles were taken into account.
