(2021-12-15)The primary purpose of this study was to investigate riser gas behavior, unloading, and the possibility of using back pressure to control and prevent riser gas unloading. Gas entering a well may be challenging to detect ...
-
(2023-08-08)This work uses a computational fluid dynamics (CFD) model to predict the leakage and rotor-dynamic coefficients of a smooth annular turbomachinery seal operating with bubbly two-phase flows for gas volume fractions up to ...
-
(2021-12-10)As the design of aerospace vehicles continues to evolve and become more complex, an accurate understanding of the physics at work in the flowfields around these vehicles is required. Alongside flight tests and wind tunnel ...
-
(2020-12-04)Performance enhancements of HVAC systems are paramount for designers and manufacturers, as HVAC accounts for nearly 50% of energy use in the United States. Building energy reductions mandated by ASHRAE standards have raised ...
-
(2016-11-18)During low speed maneuvers, such as landing and approach, a significant portion of the noise generated by transport aircraft is due to airframe noise. The leading-edge slat is a primary source of airframe noise. Previous ...
-
(2011-08-08)The design of passive heat removal systems is one of the main concerns for the modular Very High Temperature Gas-Cooled Reactors (VHTR) vessel cavity. The Reactor Cavity Cooling System (RCCS) is an important heat removal ...

(2016-12-07)Liquefied Natural Gas (LNG) pool fires pose a major risk to LNG facilities. The radiant energy from a LNG pool fire can be sufficiently high to threaten the structural integrity of the facility, plant personnel, fire ...
-
(2016-04-22)Liquefied Natural Gas (LNG) is a cryogenic liquid consisting predominantly of methane compressed to 1/600th of its gaseous volume for transportation. A release of LNG on water during marine operations can occur due to ...
-
(2013-05-31)The safety and security of liquefied natural gas (LNG) facilities has prompted the need for continued study of LNG mitigation systems. Water spray systems are widely recognized as an effective measure for dispersing LNG ...
-
(2009-05-15)An understanding of gas-liquid two-phase interactions, aerosol particle deposition, and heat transfer is needed. Computational Fluid Dynamics (CFD) is becoming a powerful tool to predict aerosol behavior for related design ...
-
(2019-10-01)Pressurized liquefied gases such as carbon dioxide are transported at a pressure above their saturation pressure. Therefore, if a pipeline transporting this substance ruptures, a large decrease in pressure occurs, causing ...
-
(2019-02-18)Fixed Bed Reactors are multi-phase reactors where flow of gas, liquid or both phase reactants occurs over a packed bed of solid catalyst. These systems are common in industry as they are easy to construct, operate and ...
-
(2012-11-02)Two topics from nuclear engineering field are included in this dissertation. One study is the air-ingress phenomenon during a loss of coolant accident (LOCA) scenario, and the other is a 5-by-5 bundle assembly problem under ...
-
(2017-05-03)Computational fluid dynamics analysis (CFD) has been employed to study the flow behavior, and dependency of pump efficiency and head on the operating conditions of the pump and fluids pumped. Commercially available ANSYS ...
-
(2016-10-10)Fluid forces acting on the shrouded centrifugal pump/compressor impellers are evaluated using the computational fluid dynamics (CFD) approach. A face-seal impeller is selected to study for predicting the rotordynamic ...
-
(2023-05-31)Low CO2 emissions processes and using renewable energy are key drivers for the future of the chemical industry. Innovation at the catalyst and reactor level is essential to address such challenges. Additive manufacturing ...
