Abstract

The thesis consists of two subtopics. The first one includes a numerical study for uniform flow past an inline oscillating square cylinder at Reynolds number of 200. The second one includes linear stability analysis (LSA) of a oscillating wake profile which is obtained by averaging the velocity profile from a flow past a stationary cylinder. The LSA of the oscillating wake profile is done with the aim of obtaining similar vortex shedding structures as obtained from the DNS results for flow past in-line oscillating square cylinder.
