Prediction of the transport properties of multicomponent dense gas mixtures
Pátek J., Klomfar J.
pages 198 - +7p, full text

An implementation of the Thorne-Enskog equation fOT the evaluation of the thermal conductivity and viscosity of high-density fluid mixture is presented. The method is based upon the rigid-sphere model of the fluid mixture suitably interpreted to apply to real fluids. The procedure requires the knowledge of the transport properties of the pure component gases at high density, the zero-density values of the transport properties both fOT the pure components and fOT their binary mixtures, and the knowledge of the virial coefficients. No dense mixture data are required. The computational method is tested against a body of experimental data on thermal conductivity obtained in the Institute of Thermomechanics in measurements on two samples of the natural gas in the temperature interval from 288 K to 360 K for pressures from 0.1 MPa to 15 MPa.
