Toward a theory of fluid mixtures with two-point interactions

We describe a fluid mixture in those situations where the microscopic particles can be considered to interact according to the laws of classical mechanics. It motivates our strong feeling that some essential changes in the form of macroscopic equations governing the behavior of a mixture of fluids are necessary (for the better understanding of the fundamental processes in the system). We provide a clue in the determination of the limits of validity of the Drumheler-Bedford approach 5] to the mixture theory and strongly generalize their main results.
