Thermal Conductivity, Viscosity, and Thermal Diffusivity Calculation for Binary and Ternary Mixtures

摘要

A mathematical model is presented for computing viscosity, thermal conductivity, and thermal diffusivity in the liquid and gas domains for pure components and mixtures. To calculate the transport properties of a real fluid, models based on Lennard-Jones intermolecular potential were applied. The new mathematical model is used for the calculation of transport properties for binary and ternary mixtures. The model is based on a new theory for mixtures. The results obtained by statistical thermodynamics are compared with the REFPROP model and show relatively good agreement.
