Turbine Instability Solution-Honeycomb Seals.
(Texas A&M University. Turbomachinery Laboratories, 1996)
A 40,000 hp steam turbine-generator in a utility service experienced a history of high vibration alarms and trips from an online vibration monitoring system. The excursions of high vibration restricted the operational load ...
The Design, Application, And Operation Of High Efficiency Turboexpanders In Process Plants.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Turboexpander thermal efficiency is an important parameter in the process design of hydrogen purification plants. When a process requires low flow and high head, expander thermal efficiency can only be improved by increasing ...
Profiled Leading Edge Groove Tilting Pad Journal Bearing For Light Load Operation.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Optimization of a leading edge groove tilting pad journal bearing for application in a small, high speed, multistage steam turbine is described. Rotordynamics constraints to meet a design objective maximum operating speed ...
Squeeze Film Damper Bearing Experimental Vs Analytical Results For Various Damper Configurations.
(Texas A&M University. Turbomachinery Laboratories, 1996)
Higher speeds, longer shafts, and increased power has made squeeze film damper (SFD) bearing performance increasingly more important to control both synchronous and subsynchronous fibration in rotating machinery. SFD bearing ...
Practical Design Against Torsional Vibration.
(Texas A&M University. Turbomachinery Laboratories, 1996)
One of the foremost concerns facing turbomachinery users today is that of torsional vibration. In contrast to lateral vibration problems, torsional failures are especially heinous since the first symptom of a problem is ...
Design And Application Of Squeeze Film Dampers In Rotating Machinery.
(Texas A&M University. Turbomachinery Laboratories, 1996)
There are common misconceptions and occasional misapplications associated with squeeze film dampers. The authors have worked for more than 25 years researching, experimenting, and applying this subject matter to all types ...
Monthly Variable-based Degree Day Template: A Spreadsheet Procedure Calculating a 3 Parameter Change-point Model for Residential or Commercial Buildings
(Energy Systems Laboratory (http://esl.tamu.edu), Texas A&M UniversityDepartment of Mechanical Engineering, Texas A&M University, 1996)
This report presents a spreadsheet procedure for calculating a variable-based degree day or three parameter change-point models using monthly utility billing data and coincident weather data. These models were used to model ...
