simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Vortex Analysis of Intra-Aneurismal Flow in Cerebral Aneurysms
This study aims to develop an alternative vortex analysis method by measuring structure ofIntracranial aneurysm (IA) flow vortexes across the cardiac cycle, to quantify temporal stability of aneurismal flow. Hemodynamics were modeled in "patient-specific" geometries, using computational fluid dynamics (CFD) simulations. Modified versions of known λ2 and Q-criterion methods identified vortex reg...
متن کامل2D FSI determination of mechanical stresses on aneurismal walls.
In this study, a fluid-structure interaction analysis based on the application of patient-specific mechanical parameters of the aneurismal walls was carried out to predict the rupture side during an abdominal aortic aneurysm (AAA). Realistic geometry of the aneurysm was reconstructed from CT data acquired from the patient, and patient-specific flow conditions were applied as boundary conditions...
متن کاملMidterm outcomes of intracranial aneurysms with bleb formation with densely coiling of the aneurismal neck or entire aneurysm
To evaluate whether the efficacy and safety of embolization of the aneurysmal neck were better than those of embolization of the entire aneurysm. Previous studies found that embolization of the aneurysmal neck can be used for treating ruptured intracranial aneurysm with bleb formation.In all, 163 patients with ruptured aneurysms with bleb formation who underwent endovascular embolization at the...
متن کاملMechanism underlying the prevention of aneurismal rupture by coil embolization.
OBJECT Endovascular treatment with Guglielmi detachable coil has been developed as a less invasive treatment for cerebral aneurysm. The aim of this study is to clarify the mechanism of the preventive effect of coil embolization. METHOD Two aneurysm models were employed. One was a T-shaped bifurcation tube with a spherical dome made of glass, which was used for the measurement of pressure and ...
