Estimation of Saturated Liquid Thermal Conductivity of Alkanes and Frons for Temperature Range over the Normal Boiling Point

Abstract

Estimation methods for liquid thermal conductivity over the normal boiling point (N.B.P.) to the critical point have not been satisfactory. In this work, using the N.B.P., liquid density at the N.B.P. and liquid thermal conductivity at the N.B.P. correlated by the function of both molecular weight and reduced boiling temperature, a new estimation method for both alkanes and frons is developed. Root mean square deviation of the proposed method is 7.42% for 861 data points. If experimental liquid thermal conductivity at the N.B.P. is used, it is 5.40 %.
