Early Detection Of Rotating Stall Phenomenon In Centrifugal Compressors By Means Of ASME PTC 10 Type 2 Test
(Texas A&M University. Turbomachinery Laboratories, 2012)
A centrifugal compressor presenting rotating stall can exhibit many problems, as limitation on its operational range, high level of subsynchronous vibrations, reduced efficiency and premature bearing wear. There are many ...

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) ...
