Woo, Jeng Won (2011-08-08)The labyrinth seal is a non-contact annular type sealing device used to reduce the internal leakage of the working fluid which is caused by the pressure difference between each stage in a turbomachine. Reducing the leakage ...
-
Basaran, Bahadir (2017-01-04)There is a necessity to use artificial lift when the natural drive of oil is not strong enough to push the oil from the well bottom to the surface. Electrical Submersible Pump (ESP) systems have been used far and wide by ...
-
Ustun, Serafettin (2012-10-19)Annular seals are devices, which are used in turboMachinery systems to reduce the flow leakage, and to provide better dynamic stability to the system. Leakage flow can strongly affect cooling quality, heating balance, and ...

Chadha, Raman (Texas A&M University, 2007-04-25)High efficiency air blowers to meet future portable aerosol sampling applications were designed, fabricated, and evaluated. A Centrifugal blower was designed to achieve a flow rate of 100 L/min (1.67 x 10^-3 m^3/s) and a ...
-
Polley, Nolan Lee (2012-02-14)Detonation diffraction has been, and remains, an active area of research. However, detonation diffraction into a confined volume, and specifically the transformation of a planar detonation into a cylindrical detonation, ...
-
Nelson, Brent (2010-01-15)For an effective Doppler Global Velocimeter (DGV), there is a requirement to accurately record and tune the frequency content of the laser used. The laser used for this experiment was an ND:YAG. Adjusting the mean frequency ...
-
Chang, Thomas Ping-Kan (Texas A&M University. Libraries, 1983)A better characterization of the mean flow systems occurring in the discharge flows of rotating impellers can advance the knowledge of mixing mechanisms in agitated vessels. Since the flow field is rather complex, the ...
-
The effects between two slotted plate flow meter under single, two, three components flow condition Park, Sang Hyan (Texas A&M University, 2005-02-17)In previous work on the slotted flow meter, repeatibility and reproducibility were studied under different flow conditions and different configurations. In accordance with previous work, the effects of the distance between ...
-
Tanvir, Hossain Ahmed (2012-07-16)Labyrinth seals are often utilized in locations where contact seals cannot be utilized due to the large displacements of the rotating shaft. The performance evaluation of a labyrinth seal is very important to make sure ...
-
Berchane, Nader Samir (Texas A&M University, 2005-02-17)The pressure distributions and forces presented in a thesis by Hossain [1] for a centrifugal pump illustrated a somewhat complex inter-relationship between various geometric and operating parameters of the pump studied. ...
-
Dismuke, Colin Patrick (2012-07-16)The purpose of this thesis is to describe the three-dimensional velocity flow field measurements in the vicinity of the inlet mouth of a cutterhead suction dredge. Using acoustic Doppler velocimeters (ADVs), an accurate ...
-
Suryanarayanan, Arun (Texas A&M University, 2004-11-15)In any rotating machinery, the geometry of the seal influences the extent of systemleakage. The path taken by the flow in the clearance volume is dependent on the seal and rotor profile. The clearance between a new ...

Experimental Measurement of Multiphase Flow and CFD Erosion Modeling in Electrical Submersible Pumps Pirouzpanah, Sahand (2015-01-05)Electrical Submersible Pumps (ESPs) are widely being used in upstream oil production. To better understand the ESP pump’s behavior, two different ESPs, MVP-G470 and ESP-WJE1000, manufactured by Baker Hughes company have ...
-
Cusano, Domenic (Texas A&M University, 2006-08-16)Instantaneous wall-pressure data were recorded for a 25% eccentric whirling annular seal for rotor speeds of 1800RPM and 3600RPM, axial Reynolds numbers of 24000 and 12000, and whirl ratios of 0.1-1.0 following the procedure ...
-
Zhang, Min (2017-11-01)This research documents the development of a 2-phase annular-seal stand (2PASS) in the Turbomachinery Laboratory at Texas A&M University to investigate the static and dynamic characteristics of annular seals operating under ...
-
Jung, Kwang-Hyo (Texas A&M University, 2005-08-29)This study presents laboratory observations of flow characteristics for regular waves passing a rectangular barge in a two dimensional wave tank. The rectangular barge was fixed and free to roll (one degree of freedom) in ...
-
Hogan, Roy Edward (Texas A&M University. Libraries, 1987)The FCVM has been used to solve both open flow problems and turbulent flow problems. The particular problems chosen for consideration were the flow between infinite parallel plates and the buoyant flow in a square enclosure. ...
-
Narayanan, Shankar Bhaskaran (2012-10-19)It is common for an oil well to produce a mixture of hydrocarbons that flash when exposed to atmospheric pressure. The separation of oil and gas mixtures on site may prove expensive and lead to higher infrastructure and ...
-
Kroupa, Ryan Daniel (2012-07-16)The use of twin-screw pumps for moving fluids is not new technology but its application to wet gas compression (high gas volume fraction [GVF]) is still considered relatively new. There are many advantages for using ...
-
Suryanarayanan, Saikishan (2010-07-14)A seal is a component used in a turbomachine to reduce internal leakage of the working fluid and to increase the machine's efficiency. The stability of a turbomachine partially depends upon the rotodynamic coefficients of ...
