Interfacial effects in the entrapment and displacement of residual oil

AIChE Journal, 1974
AbstractQualitiative theories are developed to explain the roles of surface tension and the two surface viscosities during the entrapment of residual oil by water and during the subsequent displacement of residual oil by surfactant solutions. The results are in agreement with available experimental data concerning the effects to be observed as the oil ...

Displacement discontinuity as a result of residual stress relief

2017 8th International Conference on Mechanical and Aerospace Engineering (ICMAE), 2017
The paper focuses on the problem of crack formation in an infinite strip with free sides as a result of residual stress relief. The formulas for residual stresses and for the corresponding displacements have the form of series in Papkovich-Fadle eigenfunctions.

Interfacial effects in the displacement of residual oil by foam

AIChE Journal, 1979
AbstractA qualitative theory is developed to explain the roles of surface tension and the two surface viscosities in the displacement of foams through porous media. There is a critical value of the surface tension above which a foam cannot be displaced under a given pressure gradient.

Prediction of Residual Displacement of SDOF System from its Peak Inelastic Displacement

Applied Mechanics and Materials, 2013
Residual displacement is an important measure of post-earthquake functionality of engineering structures. Empirical equations for prediction of residual displacement of SDOF system from its peak inelastic displacement were proposed through a comprehensive statistical analysis. An inelastic seismic analysis model including the P-Δ effect was employed to

Residual Mobilities

Proceedings of the 33rd Annual ACM Conference on Human Factors in Computing Systems, 2015
This paper explores discrepancies between the founding assumptions of mobile and ubiquitous computing in the western world, and the starkly different experiences of mobility and infrastructure to be found in many post-colonial environments. Based on a field study of forced mobility and technology use among populations displaced by the Hatirjheel ...

The Effects of Residual Displacement on Gap Damper Performance

2014
Previous studies on base isolated systems have shown susceptibility to large displacements at the base level, leading to pounding between structure and perimeter moat wall during a maximum considered earthquake. Undesirable pounding can lead to very high acceleration in the superstructure.

Removal of the Residual Roots Displaced Into the Maxillary Sinus via Endoscopy

Journal of Craniofacial Surgery, 2018
Abstract Minimally invasive endoscopic surgery has been developed for various indications in the craniomaxillofacial area. 1 The case report presented in this article is focused on the possibility of removing the residual roots displaced into the maxillary ...

Residual stress evaluation using shearography with large shear displacements

Second International Conference on Photomechanics and Speckle Metrology: Speckle Techniques, Birefringence Methods, and Applications to Solid Mechanics; Moiré Techniques, Holographic Interferometry, Optical NDT, and Applications to Fluid Mechanics, 1991
A newly developed optical method for the qualitative and quantitative evaluation of residual and live-load stresses is presented. The method utilizes shearography employing a large angle shearing prism which results in large shear displacements. The large angle shearing prism allows the surface speckle pattern to be referenced and mapped onto a remote,

Facile displacement of citrate residues from gold nanoparticle surfaces

Journal of Colloid and Interface Science, 2018
The stability of citrate-residues on gold nanoparticles (AuNPs) against ligand displacement has been controversial. Using AuNPs synthesized with deuterated citrate in combination with in-situ surface-enhanced Raman spectroscopic (SERS) analysis, we report that both citrate-residues and solution impurities can be simultaneously adsorbed onto citrate ...
