The interfacial property of H2O+CO2+oil three-phase systems is crucial for CO2 flooding and sequestration processes but was not well understood. Density gradient theory coupled with PC-SAFT equation state applied to investigate the tension (IFT) (hexane, cyclohexane, benzene) under conditions (temperature in range 323–423 K pressure 1–10 MPa). IFTs aqueous phase+vapor phase were smaller than H2...

Perturbed-Chain Statistical Associating Fluid Theory (PC-SAFT) coupled with the Young-Laplace equation is a recently developed equation of state (EOS) that successfully presents not only the capillary condensation but also the pore critical phenomena. The development of this new EOS allows further investigation of the heats involved in condensation. Compared to the conventional approaches, the ...

Compatible solutes like ectoine and its derivatives are deployed by halophile organisms as osmolytes to sustain the high salt concentration in the environment. This work investigates the relation of the thermodynamic properties of compatible solutes and their impact as osmolytes. The ectoines considered in this work are ectoine, hydroxyectoine, and homoectoine. Besides solution densities (15-45...

Echo methods combined with imaging evaluation allow for investigation of the inner structure of concrete members. Ultrasonic echo and impulse radar data are analysed with reconstruction calculation procedures like 3D-SAFT (Synthetic Aperture Focusing Technique) and 3D-FT-SAFT (Fourier-Transform SAFT). From the representations of the 3D-data sets (B-scans and C-scans) the location of reinforceme...

In this study, two battery models for a high-power lithium ion (Li-Ion) cell were compared for their use in hybrid electric vehicle simulations in support of the U.S. Department of Energy’s Hybrid Electric Vehicle Program. Saft America developed the high-power Li-Ion cells as part of the U.S. Advanced Battery Consortium/U.S. Partnership for a New Generation of Vehicles programs. Based on test d...

An investigation of the fuel heating, vapor formation, and cavitation erosion location patterns inside a five-hole common rail diesel injector, occurring during early opening period needle valve (from 2 ?m to 80 ?m), discharging at pressures up 450 MPa, is presented. Numerical simulations were performed using explicit density-based solver compressible Navier–Stokes (NS) energy conservation equa...

This paper focuses on the use of CO2 + SO2 binary mixture as innovative working fluid for closed transcritical power cycles with a minimum temperature above 50 °C. Starting from literature review available experimental data mixture, PC-SAFT EoS is identified suitable model to characterize behavior. Once proper thermodynamic selected this comparison between cycle and sCO2 proposed various plant ...
