A new approach to description of the pressure dependence of viscosity
نویسندگان
چکیده
Based on more precise description of the temperature-pressure dependence of entropy, we expand the Avramov’s model. In this way, viscosity or relaxation time are described with better accuracy. It is demonstrated that there is a strong relation between the fragility parameter F, described here, and the fragility parameter m, introduced by Angell, m ð13 10%ÞF. Analyses of experimental data on dielectric relaxation of phenylphthalein-dimethylether (PDE) are in agreement with the proposed model. 2009 Elsevier B.V. All rights reserved.

Modeling of Pressure Dependence of Interfacial Tension Behaviors of Supercritical CO2 + Crude Oil Systems Using a Basic Parachor Expression
Parachor based expressions (basic and mechanistic) are often used to model the experimentally observed pressure dependence of interfacial tension (IFT) behaviors of complex supercritical carbon dioxide (sc-CO2) and crude oil mixtures at elevated temperatures. However, such modeling requires various input data (e.g. compositions and densities of the equilibrium liquid and vapor phases, and molec...

A new correlation function for the calculation of viscosity for five typical supercritical gases is presented using the rainwater-Friend and modified Enskog theory. It is shown that by using accurate value for the thermal pressure and co-volume in the modified Enskog theory, this correlation function is suitable for calculation of the viscosity of supercritical gases, without any density an...
متن کاملNew Analytical Approach for Reservoir Stress Approximation Based on Acid Fracturing Data
In this research attempts were made to estimate the in-situ stresses acting on a hydrocarbon reservoir based on routine activities of acid injection in oil reservoir. It was found that the relation between the re-opening pressure of fracture and principal in-situ stresses can be estimated using rock mechanics equations for the circular underground cavities. An appropriate relation between the m...
