摘要
综合了本课题组长期对烟草导热系数的研究成果,推导出了烟叶和烟丝堆积床等效导热系数与含水率及堆密度的关系式,其计算值与实验值很吻合,并给出了根据一般含湿状态的实验数据得到的若干种不同产地不同级别烟草导热系数基准参数.这一工作为建立烟草热物性数据库奠定了的基础,并推进了对多孔介质导热系数研究的深度.
Based on the long-time research of our workgroup,an integrative relationship of thermal conductivity of tobacco with its contained water ratio and bulk density is presented in this paper.A lot of reference conductivity data was obtained about different habitats and grades by the experimental data measured in hygrometric state.Then these results make it possible to establish a tobacco thermal properties database and will be conducive to further reseach on porous medium.
