INVESTIGATION OF THE WAKE BEHIND A CYLINDER AT COINCIDENCE OF A NATURAL FREQUENCY OF VIBRATION OF THE CYLINDER AND THE VORTEX SHEDDING FREQUENCY.

Abstract

Experimental results of the investigation of the wake behind a cylinder shedding vortices at a frequency that was the same as a natural vibrational frequency of the cylinder are presented. The lateral spacial correlation of vortex shedding, the distance behind the cylinder, and the value of RMS velocity at the assumed position where the vortices start to 'roll up' were found not to deviate from the normal trend with respect to Reynolds number when coincidence of the two frequencies occur.
