应用CFD（computational fluid dynamics,计算流体动力学）仿真技术对一种新型在线梗丝分离回收装置中的气流流场、烟丝和梗签颗粒轨迹与分布规律进行了数值模拟.模拟结果表明该装置中气流分布均匀、烟丝和梗签等混合物能够有效分离,风速是影响烟丝和梗签混合物分离的主要因素.较低风速可以减少回收烟丝中的含梗量,但烟丝回收率较低;风速增大时,烟丝回收率增大,但丝中含梗率也随之增大.

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...
