Evaluation of Thermal Conductivity for Organic Liquid Mixtures

Through analysis and research of relation between thermal conductivity and density of liquid,a calculating model was proposed for evaluating the thermal conductivity of organic liquid mixtures;author has calculated the thermal conductivities for binary organic liquid mixtures having 55 systems with 377 data points by using of this model,the calculated values and experimental data are very coincident,and the total relative average deviation between them is 1.48%.the calculation accuracy is better than that of method from literature;this method is very simple and convenient,as long as the thermal conductivity data of each constituent of liquid mixtures are given,the thermal conductivity of organic liquid mixtures can be directly predicted in their deferent temperatures and constituents.
