周向加热卷烟传热过程模拟研究

Simulation on Heat Transfer Process of Circumferential Heated Tobacco Products

摘要

针对周向加热卷烟的传热过程，建立发热元件-加热卷烟的传热模型，通过数值模拟计算得到加热卷烟的温度场，并探究其随时间的变化规律；进一步分析发热元件-空气层-卷烟纸-烟丝的传热过程，计算加热卷烟系统中各部分的热量接收情况。结果表明，数值模拟结果与实验结果基本一致，各点平均相对偏差最大值仅为 2.8%；只有 11.9% 的热量经发热元件传递至卷烟纸表面，仅 8.1% 的热量被烟草段吸收。本文建立的数值模型可以较准确地预测周向加热卷烟的温度分布，并明确该类加热卷烟的传热过程和能量利用效率。

Abstract

For the heat transfer process of circumferentially heated tobacco products, a heat transfer model consisting of heating element and heated tobacco product was established. The temperature field of the heated tobacco product was calculated via numerical simulation, and its time-dependent evolution law was investigated. Furthermore, the heat transfer process across the heating element, air gap, cigarette paper and tobacco filler was analyzed, and the heat absorption of each component in the heating system was quantified. The results show that the numerical simulation data are basically consistent with experimental measurements, with the average maximum deviation merely 2.8%. Only 11.9% of the total heat transfers from the heating element to the outer surface of cigarette paper, and merely 8.1% is absorbed by the tobacco filler section. The numerical model proposed in this paper can accurately predict the temperature distribution of circumferentially heated tobacco products, and clarify the heat transfer mechanism and energy utilization efficiency of such heated tobacco products.
