INFLUENCE OF IMPELLER LEADING EDGE PROFILES ON CAVITATION AND SUCTION PERFORMANCE
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The cavitation behavior and suction performance of a pump are
largely influenced by the geometry at the impeller eye. A
number of geometric factors at the impeller eye have an
influence on cavitation, such as, the inlet ...
Upgrading To Fully-Electric Actuation and Control of Steam Turbines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2013)
The use of an electric actuator for steam turbine governor valve operation is a cutting-edge technology in steam turbine control. With this design, the use of turbine oil for turbine speed control purposes is eliminated. ...
Innovative Design in Expander Wheel-Shaft Attachment Replaces Hirth Coupling for High Speed, High Temperature and High Power Applications
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
Although this Case Study is focused on an Expander-Generator unit in a geothermal application, it’s findings can be used in all turbomachinery applications where other conventional shaft-wheel attachments are causing ...
Large Steam Turbine Vibration Resonance of Pedestal and Linkage System RCA, Detail Vibration Investigation/Measurement at Site and Countermeasures
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
