    Notes: Abstract We describe two new methods for locating the dew/bubble curves of fluids. One is a numerical method and the other an analytical method based on the use of series expansions. The utility of these two methods is illustrated by application to a simple one-component fluid model and to several model polydisperse fluids. The numerical method is based on a new geometric representation of the equilibrium conditions-similar in spirit to the geometric representations often used for solving the equilibrium conditions of pure fluids. Our calculations show that the series-expansion technique can be quite effective at producing accurate representations of the phase boundaries.

    Notes: Abstract A new geometric representation for the dew/bubble conditions of a special class of polydisperse fluids is used to develop series expansion representations for the location of the top of the dew/bubble and shadow curves and for an expansion around the top of the dew/bubble and shadow curves. An excellent approximation for the one-comonent van der Waals coexistence is given as a special illustration of the method.

    Notes: Abstract We use an extended form of the modified Enskog Theory (MET) to calculate viscosity and mutual diffusion coefficients for several binary mixtures. Second and third virial coefficients are required for the calculations. We find that the extended MET provides predictions of the shear viscosity for He-Ar and Ne-Ar mixtures with an accuracy of 2% at densities up to 6 mol · L−1. Extended MET values of mutual diffusion coefficients of binary mixtures in which the mole fraction of one component approaches zero were calculated for He-Ar and Kr-Ar mixtures. The MET values fall within 10–15% of the experimental data at densities up to 11 mol · L−1.
