不同温度条件下烟丝—发烟剂体系热物性研究
Study on thermophysical properties of tobacco and smoke agent under different temperature
摘要
Abstract
The thermophysical properties of tobacco and smoke agent (the mass ratio of glycerol andpropylene glycol is 5 ∶ 1) was measured by transient plane heat source method,and the effects of moisture and smoke agent content on reconstituted cut tobacco and fluecured were measured.The results showed that with the increase of temperature (22~75 ℃),thermal conductivity [0.06 ~0.12 W/(m · K)and 0.06 ~ 0.16 W/(m · K] and volume heat capacity [0.17 ~ 2.70 MJ/(m3 · K) and 0.15~1.45 MJ/(m3 · K)] increased;however,the thermal diffusivity decreased (0.33~0.05 mm2/s and 0.40~ 0.09 mm2/ s,respectively).With the increase of moisture content (0 % ~ 13 %),the thermal conductivity and the volume heat capacity of tobacco materials increased,however,the thermal diffusivity decreased.With the increase of smoke agent content (0 % ~25 %),the thermal conductivity of tobacco material [0.005 W/(m · K) and 0.006 W/(m · K)],the volume heat [0.106 MJ/(m3 · K) and 0.138 MJ/(ma · K)] increased slightly,but the thermal diffusivity decreased (0.069 mm2/ s and 0.069 mm2/ s,respectively).关键词
