(2021-06-21)Reaction kinetics between different rock and acid systems have been studied using the rotating disk apparatus (RDA). However, simplifying assumptions have been made to develop the current equations used to interpret RDA ...
-
(2019-09-06)Bulk-flow predictive models (BFM), though simple and fast, often fail to accurately predict the performance of gas labyrinth seals (LSs). In this work, a Computational Fluid Dynamics (CFD) analysis quantifies the effects ...
-
(2012-11-21)The determination of the leakage and consequently the friction factor is an important part of analyzing the flow through a seal. This is done experimentally by means of a flat plate tester, which allows for the simplified ...

Analysis of Two-Phase Flow Through an Electric Submersible Pump Using Computational Fluid Dynamics (2020-04-13)Electrical submersible pumps (ESP) are widely used in the oil and gas industry as a method of artificial lift. They typically consist of multiple centrifugal pump stages that convert kinetic energy to hydraulic pressure ...
-
(2022-07-26)Exploration and economic activities in the ocean environment have steadily increased in recent years, motivating the need for safer, more efficient methods to operate, survey, and gather underwater data. Autonomous Underwater ...
-
(2012-07-16)The dissertation presents a CFD approach for 3D simulation of long risers. Long riser VIV simulation is at the frontier of the CFD research area due to its high demand on computational resources and techniques. It also has ...
-
(2021-04-22)The United States and other nations plan to return humans to the surface of the Moon in this decade. On the horizon, the United States plans to send humans to the surface of Mars. Multiphase fluid systems, including boiling ...
-
(2019-07-10)Closed-fracture acidizing (CFA) is a well stimulation technique that can be applied to stimulate carbonate reservoirs at the end of acid fracturing treatment to enhance the connectivity between the acid-fracture and the ...
-
(2018-04-30)To mitigate the risk of intracranial aneurysm rupture, which can lead to severe debilitation or death, embolic devices (e.g., bare metal coils or polymeric open-celled foams) are often delivered via catheter to the aneurysm ...
-
(2018-08-22)An Ultra-High Efficiency Gas Turbine (UHEGT) technology is developed in this study. In UHEGT, the combustion process is no longer contained in isolation between the compressor and turbine, rather distributed in multiple ...
-
(2012-07-16)This work develops a discontinuous Galerkin finite element discretization of non- linear hyperbolic conservation equations with efficient and robust high order stabilization built on an entropy-based artificial viscosity ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2016)The basic consequence analysis is the initial step for any facility siting analysis. It turns out, however, that many studies quickly demonstrate that the impact to buildings can be more significant than what have been ...
-
(2013-08-12)A computational and experimental study of the Richtmyer-Meshkov instability is presented here for an inclined interface perturbation. The computational work is composed of simulation studies of the inclined interface RMI ...
-
(2019-01-30)ABSTRACT This dissertation presents a higher-order finite volume method (FVM) for computational fluid dynamics (CFD) for unstructured mesh topologies using Moving Least-Squares (MLS) as the backbone of the method. The MLS ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2016)A Computational Fluid Dynamics (CFD) model was developed to describe the behavior of a subsea gas release and the subsequent rising gas plume. Four numerical approaches were assessed for their suitability to capture the ...
-
(2015-08-11)Wind energy is the mainstream source of clean and renewable energy and it is also the fastest-growing source of sustainable energy in the world. In the Global Wind Energy Council's report in 2014, wind industry grew 44% ...
-
(Texas A&M University, 2004-09-30)The premise of the work presented here is to use a common analytical tool, Computational Fluid dynamics (CFD), along with a difference turbulence models. Eddy viscosity models as well as state-of-the-art Large Eddy ...
-
(2012-02-14)Squeeze Film Dampers (SFDs) are employed in high-speed Turbomachinery, particularly aircraft jet engines, to provide external damping. Despite numerous successful applications, it is widely acknowledged that the theoretical ...
-
(2021-10-18)One-dimensional numerical simulations are performed to analyze the ice-dust flow on cometary surfaces under the effect of gravity and cyclic heat addition. The objective is to investigate the ice formation process at the ...
