Abstract

To reveal the mass transfer mechanisms of heated cigarettes during puffing, we constructed dynamic models for the release kinetics of the cigarette core segment and mouthpiece retention segment, establishing a mass transfer model for key components of heated cigarettes. Using COMSOL Multiphysics software, we numerically solved the model to simulate the content and concentration fields of core and mouthpiece segments during each puffingcycle. Results indicated that the simulated residual amount of core segment key components during puffing closely matched experimental values, validating the dynamic model′s ability to reflect the release mechanisms of heated cigarette components. The simulated outlet release of gas phase components closely matched experimental values, validating the retention model′s ability to reflect the mouthpiece′s retention mechanism of gas phase componentsduring each puff. During puffing, the transfer efficiency of solid-phase materials near the heating element on the core segment′s outer wall was low. With increasing puffs, the concentrations of the three key components in the gas phase varied dynamically in the core and mouthpiece segments, with concentrations in the mouthpiece segment initially rising and then declining, while those in the core segment decreased from the second puff onwards. During single puffing, the concentrations of gas phase key components in the core and mouthpiece segments dynamically changed with variations in airflow velocity.
