N2 - This paper presents a computational study of laminar, viscous incompressible flow past a circular cylinder undergoing figure-eight-type motion using the two-dimensional Navier-Stokes equations. The numerical method is based on Fourier spectral method together with finite difference approximations. The response of the flow are investigated at a fixed Reynolds number, R = 200. The oscillation frequency was fixed to the vortex shedding frequency from a fixed cylinder, f0, while the amplitudes of oscillations were varied from 0.1 to 1.0a, where a represents the radius of the cylinder. The response of the flow through the fluid forces acting on the surface of the cylinder are investigated.
