Abstract:

The work presented in this paper deals with the study of thermodynamic properties of new working fluids for absorption machines, mainly for characterization of absorbent–refrigerant pairs that could improve the cycle performance. The study of atomic motion in liquids plays an important role in understanding the solid-like behavior of liquids. The accurate measurement of the energy changes due to scattering can be used to study the dynamical behavior of liquids. Measurements of the ultrasonic velocity (u), density (ρ), and viscosity (η) for binary mixtures of polyethylene glycol 200 dimethyl ether with 1-propanolover the entire composition range to investigate the nature of intermolecular interactions between the components of these liquid mixtures. Non-linear variation of derived quantities with the mole fraction supports the molecular interaction occurring between component molecules.

Keywords:

Glymes, density, ultrasonic, velocity, inter molecular interaction, thermophysical properties
