We provide a quantitative study of two types of vortex-shedding patterns that are observed within the first response range of a flexibly-mounted cylinder allowed to oscillate only in the direction of flow (the inline direction) or directions close to the inline, and undergoing Vortex-Induced Vibration (VIV). We had recently shown that within this range, two types of shedding patterns are observed: a symmetric shedding, where two vortices of the same size are shed from the two sides of the cylinder simultaneously, and an alternating-symmetric pattern, where two vortices are still shed simultaneously, but with different sizes, and their sizes alternate in each cycle of oscillations. Here, we use bubble image velocimetry (BIV) results to quantitatively study these two types of wakes. We introduce a novel method of representing the wakes that we refer to as the “Vortex Arm” representation, which makes it possible to observe the differences between the two types of shedding very clearly. We discuss the paths of these vortices in the wake and observe that while the two vortices in a symmetric shedding do not interact, the large and small vortices shed in an alternating-symmetric pattern interact, resulting in deviations from their straight downstream paths and even upstream movements of the smaller vortex. We show how the symmetric and alternating-symmetric patterns are influenced when the direction of oscillations makes an angle with respect to the direction of the incoming flow.
