Thermal conductivity and kinematic viscosity are important transport properties, and are required for designing chemical process as well as estimating dimensionless numbers such as Reynolds number, Schmidt number, Prandtl number [1]. The kinematic viscosity is evaluated using excess free energy based on modified Eyring model [2].

The authors have proposed the estimation method of thermal conductivity using excess free energy given by the following equation [3].

This paper deals with the evaluation of thermal conductivity at high pressure using the following equation.
