Understanding the stability of open shear flows such as wakes and jets has important implications for flows in industry and nature. When a fluid flows past a stationary bluff body such as a cylinder, the well-known Karman vortex shedding occurs where the shed vortices align themselves in a zigzag anti-symmetric pattern. Recent experiments and numerical simulations show that if the inlet flow is oscillatory or if the cylinder oscillates about a x position, the vortex shedding pattern can sometimes be symmetric rather than asymmetric. The goal of this thesis is to gain insight into the pattern formation process resulting in a symmetric shedding pattern. This can be achieved by carrying out a stability analysis on an oscillating wake profile.
