摘要: 为揭示加热卷烟抽吸过程中的传质机理,通过构建加热卷烟烟气关键成分的烟芯段释放动力学模型和滤嘴段逐口截留模型,建立加热卷烟中丙二醇、丙三醇和烟碱的传质模型,并采用COMSOL Multiphysics软件对模型进行数值求解,对烟支逐口抽吸过程中烟芯段和滤嘴段丙二醇、丙三醇、烟碱的剩余量及浓度场进行模拟。结果表明:模拟得到的加热卷烟逐口抽吸过程中烟芯段丙二醇、丙三醇、烟碱剩余量与实验值较为吻合,建立的动力学模型可较好地反映加热卷烟丙二醇、丙三醇、烟碱3种关键成分的释放机理;烟气丙二醇、丙三醇、烟碱逐口释放量与实验值较为吻合,建立的截留模型可较好地反映逐口抽吸过程中滤嘴段对烟气丙二醇、丙三醇、烟碱3种关键成分的截留机理;抽吸时烟芯段外壁较加热片附近固相物质传质效率低;随着抽吸口数的增加,烟气中丙二醇、丙三醇、烟碱的质量浓度在烟芯和滤嘴段呈动态变化,其中滤嘴段的质量浓度先升后降,烟芯段的质量浓度则从第2口开始减少;单口抽吸过程中,烟芯段和滤嘴段烟气丙二醇、丙三醇、烟碱的质量浓度随着气流速度的变化而发生动态变化。Abstract: To reveal the mass transfer mechanism during the smoking process of heated cigarettes, a kinetic model for the release of key smoke components in the tobacco rod section and a puff-by-puff retention model for the filter section were developed,which were used to establish the mass transfer behavior of propylene glycol, glycerol, and nicotine in heated cigarettes. Utilizing COMSOL Multiphysics software, numerical solutions were obtained to simulate the vemaining quantities and concentration fields of these components in both the tobacco rod and filter sections during each puff. The results showed that the simulated remaining quantities of propylene glycol, glycerol, and nicotine in the tobacco rod during puffing closely matched experimental values, indicating that the kinetic model effectively reflects the release mechanisms of these three key components in heated cigarettes. Similarly, the simulated release amounts of propylene glycol, glycerol, and nicotine at the smoke outlet aligned well with experimental data, demonstrating that the retention model accurately captures the retention mechanism of these smoke components in the filter during the smoking process.It was also found that the mass transfer efficiency of solid-phase substances near the outer wall of the tobacco rod was lower than that near the heating element. As the number of puffs increased, the mass concentration of propylene glycol, glycerol, and nicotine in the smoke dynamically changed within both the tobacco rod and filter sections. The concentration in the filter section initially increased and then decreased, while in the tobacco rod, the concentration began to decline after the second puff. During each puff, the mass concentrations of propylene glycol, glycerol, and nicotine in both the tobacco rod and filter sections changed dynamically with variations in airflow velocity.
