摘要

本研究采用离散元素法研究了容器尺寸对煤球内部结构的影响。研究发现,当颗粒与壁之间的摩擦阻力较大、内径较小时,煤球上部和下部的颗粒填充率差异显著。相反,当内径较大时,这种差异几乎消失。接触力的分布表明,容器内径越大,摩擦力对力传递的抑制作用越小。研究还发现,容器的高度会影响煤球的内部结构,这些结果可以用容器的高径比来概括。从根本上说,比值越大,煤球上部和下部之间的填充率差异就越大。 放大图片

Effect of the Size of Coal Briquette on Its Internal Structure

This study examines the effect of container size on coal briquette’s internal structure using the Discrete Element Method. It found that when the frictional resistance between particle and wall was large and the inner diameter small, the difference in particle filling ratio between the upper and lower parts of the briquette was significant. Conversely, with a larger inner diameter, this difference nearly disappeared. The distribution of contact force indicated that the frictional force’s inhibiting effect on force transmission lessened with a larger container’s inner diameter. The study also revealed that the height of the container affects the briquette’s internal structure, and these results can be summarized by the container’s height to diameter ratio. Essentially, a larger ratio led to a linear increase in the difference in filling ratio between the upper and lower parts of the briquette.
