(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 ...
-
(2017-12-04)Data are available for a previously tested annular seal with no swirl brakes (NSB). The NSB seal design was modified by adding slots at the inlet to produce a swirl brake (SB) seal. Tests were conducted to evaluate the ...
-
(2020-03-17)This dissertation presents methods for the prediction of the rotordynamic coefficients of annular gas seals using computational fluid dynamics (CFD). Improvements to an in-house Navier–Stokes solver for the purpose of ...
-
Characterization of Wear and Dynamic Performance of Interstage Seals for Electric Submersible Pumps (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 ...

(PLOS, 2015-07-01)Vibrissae are important components of the mammalian tactile sensory system and are used to detect vibrotactile stimuli in the environment. Pinnipeds have the largest and most highly innervated vibrissae among mammals, and ...
-
(2017-12-11)Understanding the rotordynamic and leakage characteristics of gas annular seals is important for the design of efficient and reliable turbomachinery. This work sets the foundation to advance the understanding of gas ...
-
(2013-07-31)Reducing secondary leakage is a common challenge in numerous machines, particularly in steam and gas turbines. Too large leakage in seals produces a substantial loss in efficiency and power delivery with an increase in ...
-
(2010-01-14)Adequate sealing in turbomachinery reduces secondary leakage and results in more efficient and stable systems. Labyrinth seals are most common, although brush seals are popular in specialized applications. The Hybrid Brush ...
-
(2009-05-15)This dissertation discusses research on the leakage and rotordynamic characteristics of pocket damper seals (PDS) and see-through labyrinth seals, presents and evaluates models for labyrinth seal and PDS leakage and PDS ...
-
(Texas A&M University, 2006-10-30)Non-contacting annular seals are internal sealing devices used in rotating machinery, such as multistage centrifugal pumps and compressors. Their design affects both efficiency and rotor stability. Traditional plain and ...
-
(Texas A&M University, 2007-04-25)Systematic parametric studies were performed to better understand seal-inlet rotordynamics. A CFD-perturbation model was employed to compute the seal-inlet flow disturbance quantities. Seal inlet disturbance boundary ...
-
(Texas A&M University, 2004-09-30)This thesis documents the results of high pressure testing of hole-pattern annular gas seals conducted at the Texas A&M University's Turbomachinery Laboratory. The testing conditions were aimed at determining the test seals ...
