Wettability is one of the main parameters controlling CO2 injectivity and movement plume during geological sequestration. Despite significant research efforts, there still a high uncertainty associated with wettability CO2/brine/rock systems how they evolve exposure. This study, therefore, aims to measure contact angle sandstone samples varying clay content before after laboratory core flooding...

Neovascular glaucoma (NVG) secondary to internal carotid artery (ICA) occlusion is usually resistant to treatment. We report a case of NVG with ICA occlusion improved by intravitreal bevacizumab (IVB) injection and carotid artery stent replacement (CAS), even though we did not perform panretinal photocoagulation. A 67-year-old male with NVG noted visual loss in his left eye. Magnetic resonance ...

Background: One of the most important issues for patients with osteoarthritis is reducing pain and returning them to normal life. In addition to losing weight and improving daily activities, pain management treatments may be needed. One of these treatments is the injection of hyaluronic acid gel into the knee joint, which has been studied in this study. Methods: In this stud...

In this study, complex processes in a typical Electric Arc Furnace (EAF) such as combustion, radiation, heat, and mass transfer were solved the optimum injector location was found using computational fluid dynamics (CFD). The main aim of injection optimization to improve thermal performance metallurgical process by changing angle, central angle (CAI), length. Fifteen parametric cases predicted ...

In the processing of colliding atomizers, a small change in inclination each orifice will double impact angle, seriously affecting its atomization performance. this paper, influence slight angle deviation on performance was studied steps 1°, quantitatively, for first time. The cavitation effect flow field combined with shape and parameters field. FLUENT used to simulate internal field, an indep...

The potential for hypervelocity boundary layer stabilization was investigated using the concept of damping Mack’s second mode disturbances by vibrational relaxation of carbon dioxide (CO2) within the boundary layer. Experiments were carried out in the Caltech T5 hypervelocity shock tunnel and the Caltech Mach 4 Ludwieg tube. The tests used 5-degree half-angle cones (at zero angle of attack) equ...

ABSTRACT In the process of oil and gas extraction, a system that uses pump reversing mechanism to achieve high-efficiency export gas–liquid mixture is devised. A ejector fitted in front device boost pressure inside tank order store more under given volume. To meet working conditions transport obtain larger outlet better ejection performance, this paper investigates effect pressure, ratio throat...

Aiming at the influence factors and their action regulation of slope stability in coal measure strata Beijing–Hong Kong & Macao Expressway, characteristics injection dip angle rock stratum, thickness strength parameters soft interlayer, height size on safety factor are systematically studied by using limit equilibrium method theory. The height, weak interlayer shear with different angle...

in this work, result of experimental investigation on interaction of fuel spray generated by a swirled type injector, with air motion in a prototype cylinder are presented. experiments were carried out by planar imaging and particle image velocimetry (piv) techniques in order to provide information about the spray structure evolution and instantaneous velocity distribution of air motion and fue...

The study of interactions of jet into cross flow at different longitudinal and transverse angles of jet was studied. The following components were designed and constructed: a low velocity wind tunnel to produce the uniform flow, a flat plate with a traverse injection system to simulate the jet injection, and a spatial rake to measure the total pressure. The tests were carried out at longitudina...
