Study on heat transfer process of a heat not burn tobacco product flow field

摘要

A new-style cigarette works by a battery-powered device heating cut-tobacco to generate an aerosol. This product heats the tobacco at low temperature and produces less harmful and potentially harmful constituents (HPHCs). In this paper, a heat not burn tobacco product has been designed, and the heat transfer process in the cigarette has been studied based on a porous medium theory. Both of viscous resistance and inertia force effect on pressure gradient have been considered using Darcy-Forchheimer model. After numerical simulation the process of gas traversing the cut-tobacco medium, the temperature field distribution has been acquired in the new-style cigarette. The result shows the heating system of the heat not burn tobacco product satisfies the demand of temperature control. The aerosol of the new style cigarette can reduce the yield of tobacco combustion produces.
