摘要
本研究获得了推算二元和n元有机混合液体导热系数的精确公式。该式的计算值与其他推算式的计算值和152种有机混合液体的2000点的测定值进行了比较。比较结果表明,本推算式的精度比NEL,Jardan-Coates,Filippov,Li等式和指数关联式的精度都高,本式算值与测定值之间偏差约±2％,测定值精度约±1.5％。
A exact formula for predicting thermal conductivity of binary and manifold mixtures of organic liquid has been derived in this study.The calculated values by our formula have been compared with some values calculated by other formulas and more 2000 data measured in 152 kinds of mixtures of organic liquid. The results of comparison show that our formula has higher accuracy than NEL's, Jardan-Coates's Filippciv's, Power law, and Li's formulas, the deviation between calculated values by our formula and experimental data is about +2%. The accuracy of the experimental data is about ±1.5%.
