Abstract

This paper presents a preliminary results of laminar, viscous incompressible flow past a circular cylinder undergoing circular motion at fixed Reynolds number, Re = 180. The oscillation frequency was chosen to be around the vortex shedding frequency from a fixed cylinder, f0 = 0.0951, while the amplitudes of oscillations were varied from 0.6a to 1.0a, where a represents the radius of the cylinder. The motion is described using the two-dimensional Navier-Stokes equations. The numerical method is based on Fourier spectral method together with finite differences approximations. The response of the flow through the fluid forces acting on the surface of the cylinder as well as the occurrence of the lock-in phenomenon are investigated.
