- 中文摘要: 本研究已成功的應用基團貢獻方法建立了預測有機化合物液體熱傳導度模式,其中利用154種有機化合物液體熱傳導度的1051個實驗數據,共回歸出24種基團的最佳預測常數,再配合以預測模式,估算此154種有機化合物1051個液體的熱傳導度,所得的總共平均絕對偏差是4.05%。本方法很容易使用,只須知道化合物的分子量及各基團的數目,而不須要借助任何其他物性參數便可以準確的預測有機化合物液體的熱傳導度。
- 英文摘要: A group contribution method has been developed for predicting the thermal conductivity of organicliquids. Predictive values for 24 organic groups were derived from 1051 experimental liquid thermalconductivity data on 154 organic compounds. The various group values were presented as cubic polynomialexpressions and can be used to estimate the liquid thermal conductivity at normal pressure. In this research,1051 data points on 154 organic compounds were examined by using the proposed method; the averageabsolute deviation between the predicted and the observed values were found to be 4.05%. The proposedmethod is completely generalized and fiarly easy to use. The input constants needed are the group numbersin a compound and the molecular weight of that compound. No other physical properties are required inusing this predictive method.
