Numerical Simulation On A Pump Operating In A Turbine Mode
(Texas A&M University. Turbomachinery Laboratories, 2007)
This paper deals with pump as turbine (PAT) as a feasible solution to the energy problems in rural and hilly areas. PAT provides an economical alternative to actual turbines especially for pico and microhydropower generation. ...
Multiphase Pumps
(Texas A&M University. Turbomachinery Laboratories, 2007)
Centrifugal Impeller Failure via a Thermite Reaction
(Texas A&M University. Turbomachinery Laboratories, 2007)
A 2500 HP integral gear compressor in an air separation plant experienced an impeller failure in the first stage of compression. The failure was extensive and took the dry air compressor off-line. Plant production was ...
Advances In Gas Turbine Couplings.
(Texas A&M University. Turbomachinery Laboratories, 2007)
Over the last 50 years industrial gas turbines have advanced significantly. Horsepower has increased 200 percent (and even higher) within the same envelope. Improvements in efficiencies and reliability (more operating time ...
Application Of Dynamic Simulation In The Design, Operation, And Troubleshooting Of Compressor Systems.
(Texas A&M University. Turbomachinery Laboratories, 2007)
Dynamic simulation with rigorous mathematical models allows for evaluation of compressor performance under nonsteady-state conditions. It has become a powerful tool in the design of compressor antisurge protection, evaluation ...
Surveying Tilting Pad Journal Bearing And Gas-Labyrinth Seal Coefficients And Their Effect On Rotor Stability.
(Texas A&M University. Turbomachinery Laboratories, 2007)
The evaluation of rotor system stability, which has become an essential part of rotordynamic analyses and rotating machinery design, relies heavily on the bearing and seal dynamic coefficient modeling to obtain an accurate ...
On The Potential Of Metal And Ceramic Based Abradables In Turbine Seal Applications.
(Texas A&M University. Turbomachinery Laboratories, 2007)
Abradable seals are employed in turbomachinery to reduce leakage gaps between stationary and rotating parts to improve efficiency and stall margin. Thermally sprayed abradable seals have been used in the compressor section ...
Reciprocating Compressor Condition Monitoring.
(Texas A&M University. Turbomachinery Laboratories, 2007)
Technology for reciprocating compressor condition monitoring has been around since the 1950s. However until the last 15 years or so it seemed that only the pipeline companies spent much effort on this activity. Technology ...
Rotor Bearing Loads With Honeycomb Seals And Volute Forces In Reinjection Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2007)
The calculation for unbalance response of a rotor starts by calculating the bearing load to provide the basis for the bearing stiffness and damping characteristics. Measurements in test rigs at a major Texas university ...
Case Study: Charge Compressor Turbine Vibration - Diagnostic/Risk Assessment
(Texas A&M University. Turbomachinery Laboratories, 2007)
Reducing downtime and sustaining high production rates are essential for companies to remain competitive. A 36MHP steam turbine experienced sudden high vibration. Through use of vibration analysis, selective external case ...
