Dynamic Stress Measurement Of Centrifugal Compressor Impeller And Study For Strength Criteria Based On Correlation By Unsteady CFD
(Texas A&M University. Turbomachinery Laboratories, 2010)
Based on the development of numerical analysis techniques over the past decade, the engineer can easily model the internal flow conditions and vibration characteristics of turbomachinery. When focusing on vibration response ...
Modeling Of Rotor Bow During Hot Restart In Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 2010)
Rotor bow during hot restart is a common cause of high vibrations in turbomachinery. It may occur after the shutdown of a machine operating under load, if the rotor is left cooling in standstill condition (no turning gear) ...
Shop Acceptance Testing Of Compressor Rotordynamic Stability And Theoretical Correlation
(Texas A&M University. Turbomachinery Laboratories, 2010)
This paper presents the rotordynamic stability testing of a nine-stage centrifugal compressor used for hydrogen recycle service. The machine tested was of a basic design and employed no damper bearings, damper seals, shunts ...
Measurement Of Dynamic Performance Of Large Tilting Pad Journal Bearing And Rotor Stability Improvement
(Texas A&M University. Turbomachinery Laboratories, 2010)
Capacities at today’s modern ethylene and refinery plants have steadily increased, giving rise to a growing demand for larger compressors and more powerful drivers all of which require larger rotating parts. In keeping ...
Centrifugal Compressor Evolution
(Texas A&M University. Turbomachinery Laboratories, 2010)
This paper addresses the advancements that have been made during the past 50 years in the design, analysis, and manufacturing methods for centrifugal compressors. The paper provides a historical perspective on these ...
Dramatic Reduction Of Gas Turbine Fouling With Hepa Composite Membrane Air Intake Filters
(Texas A&M University. Turbomachinery Laboratories, 2010)
Gas turbines are protected by air inlet filters that remove particulate contaminants to prevent blade fouling and erosion. The most common filters used today are medium grade filters, which are insufficient to capture ...
Enhancing Performance Of Materials In Turbomachinery: A Review Of Coating And Surface Modification Technologies
(Texas A&M University. Turbomachinery Laboratories, 2010)
Despite best efforts in choosing a suitable alloy, it is frequently impossible to find a single material that is ideal for the particular application in a centrifugal compressor or steam turbine. In these situations, a ...
An Engine Driven, High Pressure Reciprocating Type Injection Gas Compressor Design
(Texas A&M University. Turbomachinery Laboratories, 2010)
A 10,000 psi high pressure natural gas injection compressor train was procured, manufactured, tested and installed in the Boquerón production facility in Eastern Venezuela. The injection machinery consisted of three (3) ...
Application Of Repairs To Turbomachinery Equipment In Oil Refinery, Chemical, And Power Generation Plants
(Texas A&M University. Turbomachinery Laboratories, 2010)
In today’s marketplace the repairs of various components especially long lead items for turbomachinery equipment are an important factor for the maintaining reliability and performance of the equipment. This paper will ...
Unsteady Flow Field Measurements In An Industrial Centrifugal Compressor
(Texas A&M University. Turbomachinery Laboratories, 2010)
Unsteady flow field measurements of both static and total pressure, and discharge angle have been carried out downstream of an industrial centrifugal impeller. Phase-resolved measurements were performed using a cylindrical ...
