摘要
为探寻加热不燃烧卷烟逐口抽吸烟碱的释放规律,依据经典导热方程和Arrhenius定律分别确定立了烟支内部的传热传质方程,构建了加热不燃烧卷烟传热传质的数值模拟模型,利用正交设计对实验数据的拟合确定了烟碱传质动力学参数。对模型在加拿大抽吸模式下烟支内部温度场分布、烟碱释放和剩余浓度、烟碱逐口抽吸质量进行计算。结果表明,模型能够较好地实现预测计算,烟碱逐口抽吸质量模拟结果与实验结果的均方根误差为0.0121mg;烟芯内部温度变化曲线模拟值与实验值的最大误差百分比为6.1%;烟芯内部温度分布与释放特性严格对应,气体入口处烟碱的释放较差。
In order to explore the release law of nicotine in HNB cigarettes puff-by-puff,the heat and mass transfer equations inside the cigarette were determined according to the classical heat conduction equation and Arrhenius law,respectively,and the numerical simulation model of heat and non-burn cigarette heat and mass transfer was constructed in the paper.The nicotine mass transfer kinetic parameters were determined by fitting the experimental data using an orthogonal design.The temperature field distribution inside the cigarette,nicotine release and residual concentration,and puff-by-puff quality of nicotine under the Canadian smoking mode were calculated.The results show that the model can better realize the prediction calculation,and the root mean square error between the simulation results of the nicotine puff quality and the experimental results is 0.012lmg;The maximum error percentage between the simulated value and the experimental value of the internal temperature change curve of the wick is 6.1%;The internal temperature distribution of the wick corresponds strictly to the release characteristics,and the release of nicotine at the gas inlet is poor.
