摘要
Abstract
The numerical simulation about a new on-line cut tobacco and cut stem mixture separation device was studied,where the velocity field and tobacco particle trajectory were obtained by computational fluid dynamics software.The results show:the velocity field is uniform in the duct.The mixture of cut tobacco and cut stem can be separated effectively.Velocity is the main factor affecting the separation of tobacco and stem mixture.The amount of cut stem and the recovery rate of cut tobacco can both decease in the relatively low velocity.Conversely,the amount of cut stem and the recovery rate of cut tobacco can increase.关键词
