Development Of A High Pressure Rotordynamic Test Rig For Centrifugal Compressors Internal Seals Characterization
(Texas A&M University. Turbomachinery Laboratories, 2011)
The current centrifugal compressor design for the Oil & Gas market is more and more challenging since the cost requirements and the presence of many competitors is pushing towards casing size reduction and rotational speed ...
Full Load Testing Of A 12.5 MW Vertical High Speed Subsea Motorcompressor
(Texas A&M University. Turbomachinery Laboratories, 2011)
In late 2006 Authors’ company was awarded a contract for the motorcompressor for the Ormen Lange Subsea Compression Pilot. This Pilot represents the first subsea motorcompressor unit ever built in a fully marinized version ...
STALL INDUCED AERODYNAMIC FORCING AND ROTOR VIBRATIONS IN A MULTISTAGE CENTRIFUGAL COMPRESSOR
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
The Oil & Gas industry is looking with increased interest

machine is generally limited at the ...
Centrifugal Compressor Rotordynamics in Wet Gas Conditions
(Texas A&M University. Turbomachinery Laboratories, 2014)
A new technology challenge in centrifugal compressor design and operation is the condensate phase management. End users (especially in offshore and subsea operations) are more and more interested to have a Wet Gas Compression ...
Instability Of A High Pressure Compressor Equipped With Honeycomb Seals.
(Texas A&M University. Turbomachinery Laboratories, 2003)
A two casing (three-stage) high-pressure injection compressor train driven by a gas turbine via a gearbox was full load and full speed performance tested to demonstrate satisfactory aerothermal and rotordynamic performance. ...
Design Validation of High Speed Ratio Epicyclic Gear Technology in Compression Systems
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 5: Epicyclic gear technology is a key factor to support thcompression growth strategy in electrified applications, due to the ever increasing transmission ratio required to meet the high compressor speeds. The paper ...
Development And Application Of A Vertical High Speed Motor-Compressor Simulator For Rotor Drop Onto Auxiliary Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2009)
During the conceptual development of a subsea motor-compressor prototype running on active magnetic bearings, the emergency landing on the catcher bearings was identified as a potential technology gap. This is because the ...
Rotordynamic Test Results From a High Flexibility Ratio - High Pressure Fully Instrumented Centrifugal Compressor Test Vehicle
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
Closed centrifugal compressor impellers have been manufactured using several methods through the years. Due to limitations of the materials and machining processes, most of these impellers have been manufactured in what is considered two piece or three piece methods. Despite the vast amount of experience with traditional construction methods, there is a drive to move towards one piece construction, where there are no joints and, in theory, lower probability of preexisting defects. Typically, the impellers that are being offered as one piece are those with relatively large openings where 5-axis milling machines can be utilized. This paper investigates several alternative methods to manufacturing small tip opening impellers as a single piece. The methods discussed include Electrical Discharge Machining (EDM), investment casting, Hot Isostatic Pressed Powder Metal (HIP’d PM), and Direct Metal Laser Sintering (DMLS).
