摘要：

加料滚筒是一个复杂的动态过程,为揭示加料复杂系统的内在关系和规律,建立烟丝、气体流固耦合模型,文中借助计算机专业 CFD软件运用Fluent模拟滚筒加料机内颗粒物料运动特性,揭露滚筒加料机内部颗粒物料运动轨迹的研究。结果表明,建立的流固耦合模型对制丝加料过程的仿真模拟有效、可信度高,揭示了滚筒内部烟叶运动状态。同转速下烟叶颗粒粒径越小,松散越均匀;滚筒转速对烟叶颗粒运动轨迹的影响不大。

Abstract:

Charging materials in drum is a complex dynamic process. In order to reveal the inherent laws and physics of the charging system, the fluid-solid coupling model of air flow and tobacco was established by using professional CFD software Fluent to simulate the kinetic characteristic and trajectory of granular materials in charging drum. The results showed that the fluid-solid coupling model used to simulate the tobacco charging process was reliable and valid, revealing the motion state of tobacco leaves in the drum. Moreover, at the same speed, the smaller the particle size of tobacco leaves, the more uniform the looseness. The rotational speed of the drum had little effect on the trajectory of tobacco granules.

Key words: tobacco machinery, chargingdrum, Fluent, the fluid-solid coupling, CFD, the trajectory of granule
