Wu, Tingcheng (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 ...
-
Lu, Xueliang (2020-05-14)In the subsea oil and gas industry, multiphase pumps and wet gas compressors are preferred technologies as they eliminate a conventional liquid-gas separation station to save up to 30% of capital investment. Seals in ...

Gutierrez, Noble Knight (2023-05-05)Solid deposits form when a lubricant undergoes thermal breakdown due to high-temperature conditions and can cause adverse operational effects within engines. A collection device designed to allow coke to form on its surface ...
-
Koosha, Rasool (2020-10-15)A self-equalizing tilting pad thrust bearing (TPTB) improves operation reliability by adjusting its pads to accommodate thrust collar tilt, and hence removing a source of frequent wearing. Although recent literature states ...

McCray, Marshall Cameron (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 ...
-
Riefer, Joshua (2018-07-30)Perceptive vocabulary for musical instrument sounds often lacks structure and standardization. Descriptors often convey qualitative appreciations, varying from listener to listener. Defining tone in terms of quantitative ...

Analysis of Two-Phase Flow Through an Electric Submersible Pump Using Computational Fluid Dynamics Katke, Tanvi (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 ...

San Andres, Luis; Delgado, Adolfo (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)Turbomachinery seals are engineered to maintain efficiency and power delivery by minimizing leakage. Seals also appreciably affect the system rotordynamic behavior due to their relative position within a turbomachine. The ...

Characterization of Wear and Dynamic Performance of Interstage Seals for Electric Submersible Pumps Hure, Robert Byrd (2019-02-22)Electric Submersible Pumps (ESPs) increase head of process fluid in oil production from within the well. An ESP comprises of a pump, seal, and motor section oriented vertically. The pump section includes multiple centrifugal ...
-
Balaji, Suryanarayan (2022-07-25)This project presents the design of a compliantly damped tilting pad porous carbon hybrid gas bearing (CHGB), and a test rig to facilitate component and system level testing. The intent of such a bearing is to operate as ...

Moody, Andrew Michael (2022-12-13)The rotordynamic characteristics and leakage are presented for three damper seals manufactured by 3D printing with carbon fiber reinforced Nylon. The seals have texture patterns consisting of diamond shaped holes. The first ...
-
Thiele, Jonathan Joseph (2019-07-09)Balance piston gas seals restrict leakage at the discharge of centrifugal compressors. There are multiple types including labyrinth seals, textured seals, pocket damper seals (conventional PDS), and fully-partitioned pocket ...
-
Green, Gage Branson (2020-04-30)In 2011, a series of seismic events induced a station blackout condition at the Japanese nuclear power site Fukushima Daiichi. Without power, all three units were unable to maintain proper core cooling. To supplement the ...
-
Freyman, Thomas Paul (2020-12-01)The 2011 Fukushima Daiichi nuclear accident led to the destruction of three BWR cores and containment buildings. Despite the negative outcomes of this incident, the RCIC system for both Unit 2 and Unit 3 operated in harsher ...
-
Jung, Wonbae (2017-12-08)Despite their many advantages, bump-type foil bearings (BFBs) have issues of dryfriction during sliding contact at rotor start/stop cycles. To prevent premature wear of both shaft and the BFB, the proper selection and ...
