Abstract : A model for the prediction of the density, viscosity and thermal conductivity of non-polar fluid mixtures over the entire range of PVT states is presented. The model is based on the extended corresponding states model and covers molecular weight ranges including C20. Only pure component equilibrium data such as the critical constants are required as input to the calculation procedure--no transport data are required. Extensive comparisons with experimental data for pure fluids and binary mixtures are presented. The average percentage deviation for both the viscosity and thermal conductivity was observed to be less than 8 percent. A computer program (TRAPP) which performs the calculations reported in this manuscript is described and listed in the Appendices. (Author)
