Thermal conductivity and kinematic viscosity are important transport properties, and is required for designing chemical process as well as estimating dimensionless numbers such as Reynolds number, Schmidt number, Prandtl number. The kinematic viscosity is evaluated using excess free energy at activated state based on Eyring model [1,2].
The excess free energy can be evaluated using vapor-liquid equilibrium data.
For regular solution, k is -1/2.5 [1].
The authors have proposed the estimation method of thermal conductivity for ideal solution using the following equation [3].
Then we discuss the excess properties by the following equation.
This paper deals with the evaluation of thermal conductivity using vapor-liquid equilibrium data.
The kâ is binary constant for thermal conductivity. The kâ values have been determined using thermal conductivities data [4] and vapor-liquid equilibrium data [5] for binary systems. The number of binary systems discussed in this paper is 20.
