In actual production tests, there are large fluctuations in the ventilation rate and smoking resistance of cigarettes. In this paper, fluctuations in ventilation rate and smoking resistance are attributed to variations in the number of ventilation holes in the joint paper and the porosity of each component. The effects of small changes in porosity of each component were analyzed by using computational fluid dynamics methods. The results showed that the difference in the effective number of ventilation holes caused by the gluing process had little effect on the ventilation rate and smoking resistance of cigarettes in the practical production process. The smoking resistance is mainly affected by the structural parameters of filter tow and cut tobacco section in the length direction of cigarettes, the porosity of cigarette paper and packaging paper is positively related to the cigarette ventilation rate, the porosity of cut tobacco and the porosity of filter tow are negatively related to the cigarette ventilation rate, and the influence of shaped paper is the smallest. The results can provide technical and theoretical basis for the optimization of cigarette process parameters and the stabilization of ventilation rate.
在实际生产测试中，卷烟的通风率和吸阻存在较大波动。本文将通风率和吸阻的波动归因于接装纸通风孔数量的变化以及各组分的孔隙率。采用计算流体动力学方法分析了各组分孔隙率微小变化的影响。结果表明，在实际生产过程中，由粘贴工艺导致的通风孔有效数量差异对卷烟的通风率和吸阻影响较小。吸阻主要受卷烟长度方向上滤嘴丝束和烟丝段的结构参数影响，卷烟纸和包装纸的孔隙率与卷烟通风率呈正相关，烟丝孔隙率和滤嘴丝束孔隙率与卷烟通风率呈负相关，成型纸的影响最小。研究结果可为卷烟工艺参数优化及通风率稳定提供技术和理论依据。
