Abstract

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
