| 摘 要： | 在新型烟草加香加料设备研制过程中,为解决多管送风导致孔板布风不均的问题,采用计算流体力学(Computational Fluid Dynamics,CFD)软件Fluent对原设计结构中的流场进行了仿真研究.仿真结果表明,布风室内气流合流产生的漩涡和筒内不良气泡特性的产生是导致布风不均的主要原因,对此提出了加装隔板分割布风室、对各布风室独立送风的改进措施.试验数据表明,改进后布风室两侧进风管道的风速差由2.1,1.5,14 m/s降低到0.5,1.3,1.0 m/s,阻止了布风室内涡流和加香加料筒内不良气泡特性的产生,改善了筒内气固两相混合的均匀性和规律性.

| Abstract: | In the development of a new tobacco flavoring and casing cylinder,the flow field in the existing cylinder was simulated and investigated with CFD software,FLUENT.The simulation results showed that the vortexes resulted from the convergence of different air streams in the air distribution chamber and the undesirable characteristics of the air bubbles in the cylinder were the main reasons causing uneven air distribution.Therefore,the air chamber was partitioned and air was supplied to each compartment indepen... |
