Thermal Conductivity of Gaseous HFC161

根据瞬态热线法原理,搭建了新的热导率测量实验装置。用标准物质氮气对该实验台进行了检验,结果表明该实验台测量结果准确可靠。对HFC161气相热导率在温度范围为253~373 K、压力范围为139.9~4470.3 kPa进行了实验测量,并将实验结果拟合成温度与压力的多项式,为以后的进一步研究提供计算依据。

According to the transient hot wire method,a new apparatus was designed for measurement of thermal conductivity.The experiment system was tested with the standard matter nitrogen.And it indicated that the results measured by the new apparatus were accurate and reliable.The thermal conductivity of gaseous HFC161 was measured over the temperature range from 253 K to373 K and at pressure from 139.9 kPa to 4470.3 kPa.The results were fitted by a polynomial as a function of temperature and pressure for future research.
