โœฆ Synopsis

The introduction of grid-turbulence in the free-stream flow resulted in a marked change of the vibrational response of tubes when placed in a single row and in some, only, of the two-row arrangements studied. A reduction of the maximum amplitudes was observed for the one-row arrays depending on the tube pitch and tube flexibility.

It is well-known that a cylinder bundle vibrates in a cross flow. Studies of the vibration have been made by Roberts, Connors, Blevins et aL, and it has been established that the vibration is a fluid elastic vibration. However, their theory, which is based on quasi-static fluid forces, does not alwa
