AEROELASTIC COUPLING AND INSTABILITY IN TUBE ARRAY

• Abstract:

  Flow speed and frequency dependencies of vibration transfer by flowing air between tubes in a row are presented. The transfer is increasing linearly with dynamic pressure, but with frequency dependence it is a bit more complicated. Also time histories and frequency spectra of the tube vibration are caught and commented.
