Abstract |
Most structures and equipment used in
nuclear power plant and process plant, such as reactor
internals, fuel rods, steam generator tubes bundles,
and process heat exchanger tube bundles etc., are
subjected to Flow Induced Vibrations (FIV). Costly
plant shutdowns have been the source of motivation
for continuing studies on cross-flow induced
vibration in these structures. Damping has been the
target of various research attempts related to FIV in
tube bundles. A recent research attempt has shown
the usefulness of a phenomenon termed as "thermal
damping". The current paper focuses on the
modeling and analysis of thermal damping in tube
bundles subjected to cross-flow. It is expected that
the present attempt will help in establishing improved
design guidelines with respect to damping in tube
bundles.
