Application of the Kirkwood Buff theory of solutions to a binary mixture of interest for refrigeration systems and heat pumps

Abstract

Kirkwood Buff Integrals (KBI's) play a significant role in understanding and characterizing interactions in liquid systems. In the present context, these integrals have been evaluated for a special group of polymers, called glymes, which have been extensively used in various industries including refrigeration systems and heat pumps. The importance of this method lies in using just the initial parameters of the experimental values of ultrasonic velocity, density and viscosity for evaluating the KBI's from reported thermodynamic data. Studying the behavior of these Integrals leads to a deeper understanding of these systems using which an attempt can be made to predict the right composition for which the system behaves most efficiently.
