推算有机卤代烃导热系数的新方法——修正 Viswanath 法

Improved Correlation for Estimating Thermal Conductivity of Halides

在推算饱和液体导热系数的Ｖｉｓｗａｎａｔｈ方法的基础上，参考了Ｌａｔｉｎｉ修正式的思想，对Ｖｉｓｗａｎａｔｈ方程的原形作了进一步修正，使推算范围从液态扩展到低压下的气态．在提高原方程精度的基础上，改善了预测性和外推性，使其计算平均偏差小于６％．该修正式可用于甲烷系卤代烃、乙烷系卤代烃（氟里昂）在上述范围内的导热系数的推算．

Existing methods for correlating thermal conductivity such as those of Viswanath and Latini are improved so that the calculation for the saturated liquid state could be extended to the low pressure gas state. Estimates for the thermal conductivity of halides are within 6% of the experimental values.
