.... For the first condition, which occurred at low flow velocities where the natural vortex shedding frequency was below the acoustic resonance frequency, fully developed vortices formed in both the gap region between the cylinders and in the wake. These vortices were found to be in phase with each other...

... in many circumstances. The phenomenon is nonlinear and involves the rolling up of the shear layer to produce vortices. For small amplitudes the shear layer oscillations add energy to the system and, thus, act as a source of negative unstable damping. However, for large amplitudes the shear layer absorbs...

... is investigated experimentally. As a result, the following phenomena are clarified. Three types of flow patterns were observed: flow pattern A, with unsteady vortices, flow pattern B, with a single swirl and a vortex, and flow pattern C, with twin swirls. The flow pattern changes from A to B or C as the amplitude...
