Conformal‐Solution‐Theorie für Mischungen konvexer Moleküle

Abstract

Abstract The Hard Spheres Expansion Conformal Solution Theory [1], originally developed to predict the thermodynamic properties of mixtures of spherical molecules, is generalized for the treatment of fluids that are composed of particles interacting via Kihara type potentials [2].—A perturbation expansion is generated by dividing the intermolecular pair potential into a repulsive and an attractive part. The hard‐core reference system is represented by a mixture of hard convex bodies. It's thermodynamic functions are obtained from a new accurate equation of state. The attractive contributions are evaluated from the known attractive interactions of a pure reference fluid using the principles of conformal solution theory and a new type of pseudoparameters.—A method for the determination of temperature and density dependent effective hard‐core parameters is presented.
