Electromagnetic Effects On The Torsional Natural Frequencies Of An Induction Motor Driven Reciprocating Compressor With A Soft Coupling
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The electromagnetic field in the air gap of an electric motor is responsible for producing torque between the rotor and stator. The analysis and design of motor-driven equipment trains can be improved by including this ...
Application of Dynamic pressure-balanced Seals in a Multi-stage Centrifugal Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Test results for an ASME Power Test Code 10 (PTC) Type 1 test of a 4,500 psia (310 Bara) discharge pressure gas lift centrifugal compressor outfitted with dynamic pressure-balanced seals at the impeller eyes; shaft interstage ...
Full Scale Validation Of A High Pressure Ratio Centrifugal Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
The present paper describes the test activities which have validated a new compressor architecture, developed by the OEM, which is able to deliver a higher pressure ratio in a single casing with respect to traditional ...
Squeeze Film Dampers: A Further Experimental Appraisal Of Their Dynamic Forced Performance
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Squeeze Film Dampers (SFDs) are effective means to ameliorate rotor vibration amplitudes and to suppress instabilities in rotor-bearing systems. A SFD is not an off-the-shelf mechanical element but tailored to a particular ...
A CFD Primer: What Do All Those Colors Really Mean?
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
This tutorial provides a general overview of computational fluid dynamics (CFD). It is not intended for CFD experts but rather for those seeking answers to questions such as: What is the role of CFD in the design / analysis ...
Revolving Vane Mechanism: A Novel Pumping Mechanism
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 25
Evaluation of Various Methods for Manufacturing One Piece, Small Tip Opening Centrifugal Compressor Impellers
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 12: 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 ...
Effect of Inlet Cooling on the Performances of Isotherm Main Air Compressor Used for ASU Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 10: Main air compressors used for air separation units (ASU) applications have a suction at ambient conditions and deliver air to a pressure range between 5.6 ~ 6.5 bara. Therefore, the performances of the compressor ...
Development of High-Pressure Ratio and Wide-Operating Range 700bar Compressor
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Lecture 1: Pre-Salt development projects continue to expand offshore Brazil into ever deeper waters year after year. Consequently, the required Discharge Pressures for Re-Injection Compressors aboard FPSO’s are likely to ...
