FLUID-STRUCTURE INTERACTION AND VIBRATION CONTROL

We can successfully predict deformations of rotating disks with our comprehensive modeling of vibration: Disk eigen modes (frequencies) are excited by repeatable interaction of rotating flow with enclosure, whereas disk broad-band vibrations
are excited by disk turbulent boundary layer.

Measured vibrations of a disk excited by airflow shown above by squares, predicted shown by the solid line.
