Experimental and numerical study on thermal conductivity enhancement of reconstituted tobacco leaf
摘要
Abstract
To address issues such as the low thermal conductivity and bland taste of reconstituted tobacco leaf(RTL),thermal conductive fillers including Al2O3,MgO,and ZnO were added to RTL to enhance its thermal conductivity.ANSYS software was used to construct thermal conductivity models for the RTL composite materials,and the errors of each model were compared and analyzed.The results show that Al2O3 had the best effect on improving the thermal conductivity of RTL.Using a mass fraction of 5%Al2O3 as filler,the thermal conductivity of RTL reached 0.452 2 W/(m·K),representing a 29.2%increase compared to unfilled RTL.The thermal diffusivity also showed significant improvement.With a 5%mass fraction filler,the thermal diffusivity of RTL filled with Al2O3,MgO,and ZnO was 0.316 1,0.364 5,and 0.288 2 mm2/s,respectively.The specific heat capacity generally showed a downward trend.RTL filled with MgO exhibited the greatest decrease in specific heat capacity,while that filled with Al2O3 showed the least decrease.At a 5%mass fraction,the specific heat capacity of MgO-filled RTL was 1.230 MJ/(m3·K).Comparing the calculation results of various thermal conductivity models,the error of the ANSYS simulation was less than 10%,while the errors of other models all exceeded 10%.This research provides a scientific basis for the industrial application of reconstituted tobacco leaf and the performance optimization of tobacco materials.关键词
