Abstract

Abstract: To reveal the influence mechanism of ventilation structure on the internal thermal flow field of heated tobacco products, a gas-solid two-phase heat transfer model based on porous media was constructed. The evolution law of the thermal flow field under different ventilation hole arrangements was investigated. The results indicated that drilling holes in the cooling section had an impact on the temperature of the tobacco section, and the cooling effect of the samples with two rows of holes was more obvious. Under the condition of the same total number of holes (both 6 holes) but different distributions, the outlet aerosol temperature of the sample with one row of 6 holes was generally higher than that of the sample with two rows of 3 holes. Moreover, the temperature decrease rate of the sample with two rows of 3 holes in the cooling section was faster, demonstrating better heat dissipation performance. Under the condition of the same number of rows (both 2 rows) but different numbers of holes per row, the variation trends of the outlet aerosol temperature for the samples with two rows of 3 holes and two rows of 6 holes were basically consistent, and the difference in cooling efficiency was not significant. The arrangement of ventilation holes significantly affected the temperature field and flow field distribution inside the heated tobacco products. Increasing the number of ventilation hole rows effectively expanded the turbulent mixing region and enhanced the heat exchange efficiency between the air and the high-temperature aerosol, thereby reducing the outlet aerosol temperature.
