摘要
将适用于两体混合颗粒流的能量均分定理推广到非均匀的复杂混合颗粒流系统 .根据混合颗粒流具有的分形特征 ,推导出颗粒流中颗粒的分形速度分布函数 ,并建立混合颗粒流有效热传导的分形模型 .由此导出质量连续分布的复杂混合颗粒流的有效热传导系数 。
The equipartition of energy applied to binary mixture of granular flow is extended to granular flow with non uniform particles. Based on the fractal characteristic of granular flow with non uniform particles, the distribution function for fractal velocity and the fractal model for effective thermal conductivity are derived. The coefficient of effective thermal conductivity is accumulated. Thermal conduction derived from motions of particles in the granular flow and the effect of fractal dimension on effective thermal conductivity are discussed.
