摘要：以加热卷烟制品为研究对象,采用计算流体力学(CFD)方法研究加热卷烟制品烟丝在加热和抽吸模式下的烟气流动和传热过程,建立了加热卷烟制品内部烟丝加热和烟气流动的数学模型。结果表明:加热卷烟制品经加热器加热后,烟丝段温度升高至493.6 K,总传热系数为3.4 W/(m~2·K);由于在抽吸模式下有烟气通过,烟丝段温度由394.1 K降低至393.8 K,但烟气流动对温度分布影响较小;从通风端到抽吸端,压力逐渐降低。
Reducing the harm of cigarette smoke to health has been widely investigated in the cigarette industry.The burning or heating mode of tobacco has a great impact on the released harmful components.Much work has been made to develop the new heated cigarette product with the aim to decrease the amount of the harmful components from the smoke.In order to investigate the characteristics of tobacco heating by the heated cigarette product,smoke flow state and heat transfer process during the smoking mode,a three-dimensional mathematical model of porous medium for tobacco heating and smoke flow in a cigarette was established.The process of heat transfer and smoke flow were numerically simulated using computational fluid method(CFD)software(ANSYS fluent).The flied distributions of temperature,velocity and pressure during cigarette heating by the heater of heated cigarette product and smoking at a constant flow rate were obtained.The results showed that the tobacco could be effectively heated to 493.6 K by the heater for heated cigarette product with a total heat transfer coefficient of 3.4 W/(m~2·K).During smoking at a constant flow rate of 17.5 mL/s,the tobacco temperature was decreased from 394.1 K to 393.8 K with a uniform radial temperature distribution,and the smoke flow had a relatively small impact on temperature distribution of the tobacco.On the other hand,the pressure was decreased from the tobacco section to holder.These results can provide the theory guidance and fundamental data for optimizing the structure of the heated cigarette product and the heating mode of tobacco to a certain extent.
