In recent years, new types of cigarettes featuring innovative designs and materials have emerged. However, the complexity of their composition, structure, and components has led to an unclear understanding of the flow and transmission processes of aerosol within the smoke. There is an urgent need to utilize new technologies, such as computational fluid dynamics (CFD), to conduct in-depth research on these processes in cigarettes. This paper establishes a three-dimensional model of the flow and transmission of smoke aerosol within a cigarette, based on the fundamental parameters of a typical cigarette and the basic physical properties of smoke aerosol. Through this model, we simulate and analyze the flow states and temperature field distributions of various typical cigarette smoke aerosols, exploring the impacts of cigarette structure, ventilation filter design, and pressure drop distribution of smoke aerosol during the smoking process on the temperature field distribution. This research lays a solid foundation for constructing and enhancing the risk assessment system for Chinese tobacco products.
