Polymer flooding is now considered a technicallyand commercially-proven method for enhanced oil recovery (EOR). The viscosity of the injected polymer solution is the key property for successful polymer flooding. Given that the viscosity of a polymer solution has a non-linear relationship with various influential parameters (molecular weight, degree of hydrolysis, polymer concentration, cation c...

The current numerical analysis was utilised to compare the hemodynamic effects caused by flow disruptions in coronary arteries with and without stenosis order evaluate importance of patient-specific using Computational Fluid Dynamics (CFD) provide information public, particularly surgeons, assist them reducing risk stenosis. Assuming is turbulent non-Newtonian viscosity, Carreau model incorpora...

Intracranial aneurysms (IA) are dilations of the cerebral arteries and, in most cases, have no symptoms. However, it is a very serious pathology, with high mortality rate after rupture. Several studies been focused only on hemodynamics flow within IA. besides effect flow, development and rupture IA also associated combination other factors such as wall mechanical behavior. Thus, objective this ...

Profile extrusion is a manufacturing process used for continuous plastics profiles with a fixed cross section. The key challenge in the development of profile extrusion dies is to design the transition region between outflow and inflow of the die in such a way, that the material velocity at the outflow is homogeneous. At the current state of the art, die design is experience based and time-cons...

BACKGROUND Guar galactomannan is a plant polysaccharide with extensive applications in food, paper, textile and petroleum industries. The main advantages for using guar are its low cost, easy availability and capacity to form viscous solutions and gels at low concentration. Additionally, chain architecture of guar galactomannan can be selectively modified to tailor properties of guar formulatio...
