摘　　要：为探究卷烟物理参数对卷烟内部气流场的影响,采用计算流体力学的方法模拟了卷烟内部烟气的流动过程,考察了卷烟材料黏性阻力系数、卷烟长度等对卷烟抽吸端压降、卷烟纸通风量和滤嘴通风量的影响,并构建了可以定量描述卷烟物理参数对卷烟内部气流场耦合作用的关联式。结果表明:①压降与烟丝、滤嘴、卷烟纸和成型纸的黏性阻力系数均呈正相关关系,卷烟纸通风量与烟丝和成型纸的黏性阻力系数均呈正相关关系,滤嘴通风量与烟丝、滤嘴和卷烟纸的黏性阻力系数均呈正相关关系。②随着卷烟长度的减小或卷烟直径的增加,压降、卷烟纸通风量和滤嘴通风量均呈减小趋势。③随着通风孔深度的增加,压降和卷烟纸通风量均呈减少趋势,滤嘴通风量呈增加趋势;随着通风孔到抽吸端距离的增加,压降和卷烟纸通风量均呈增加趋势,滤嘴通风量呈减少趋势。④所建关联式的相关系数均大于0.93,且预测值与实测值之间的相对误差均较小,可以较为准确地描述卷烟物理参数对卷烟内部气流场的耦合作用。To investigate the effects of cigarette structure parameters on the air flow field inside the cigarette,a computational fluid dynamics(CFD)method was adopted to simulate the air flow process inside a cigarette.The effects of viscous resistance coefficients of cigarette materials and cigarette length on the mouth end pressure drop and the ventilation rates of cigarette paper and filter were analyzed,and the correlation equations,which can quantitatively describe the coupling effect of cigarette structure parameters on the air field inside cigarette,were established.The results showed that:1)The pressure drop was positively correlated with the viscosity resistance coefficients of cut tobacco,filter,cigarette paper and plug wrapper,the ventilation rate of cigarette paper was positively correlated with the viscosity resistance coefficients of cut tobacco and plug wrapper,and the ventilation rate of filter was positively correlated with the viscosity resistance coefficients of cut tobacco,filter and cigarette paper.2)As the cigarette length decreased or the cigarette diameter increased,the pressure drop and the ventilation rates of the cigarette paper and filter decreased.3)As the number of ventilation holes increased,the pressure drop and the ventilation rate of the cigarette paper decreased,while the ventilation rate of the filter increased.As the distance between the ventilation holes and the mouth end increased,the pressure drop and the ventilation rate of the cigarette paper increased,while the ventilation rate of the filter decreased.4)The correlation coefficients of the established correlation equations were all higher than 0.93,and the relative errors between the predicted and measured values were small,which could accurately describe the coupling effect of cigarette structure parameters on the air flow field inside the cigarette.
