Investigation of the wake behind a cylinder at coincidence of a natural frequency of vibration of the cylinder and the vortex shedding frequency

Theory for aeolian tone intensity created by rigid circular cylinders has been found to agree quite well with experimental results. This investigation is to experimentally explore the wake of a cylinder shedding vortices at a frequency that is equal to one of the natural vibrational frequencies of the cylinder. Investigation was carried out in the following areas: 1, lateral spacial correlation of vortex shedding; 2. distance behind cylinder and value of RMS velocity at assumed position where vortices start to "roll up"; 3. observation of the phase between velocity signals at two points along a cylinder.
