flow past circular cylinder is a fundamental fluid mechanics problem of practical importance. It haspotential relevance to many practical applications such as submarines, off shore structures, bridge piers, pipelines etc. Inscientific terms, the flow around circular cylinders exhibits various important physical phenomena, such as separation,vortex shedding and turbulence in the wake, at relatively low flow speed. Building on understanding of a single stationarycylinder, many researchers have focused on multiple stationary or oscillating cylinders.The present study numerically investigates the two-dimensional laminar flow past a circular, square and elliptical cylinderforced to oscillate transverse to the free-stream. The analysis are performed at a various range of cylinder oscillationfrequency ranged between 0.8 and 1.2 of the natural vortex shedding frequency, and the oscillation amplitude is 50% ofthe cylinder diameter at fixed Reynolds number of 185 showing the typical two-dimensional vortex shedding. Numericalstudy carried out with CFD (Computational Fluid Dynamics) tools FLUENT with dynamic mesh. UDF (User DefinedFunction) are incorporated with FLUENT to give simple harmonic motion to cylinder.
