RESUMO

The goal of this work is to study through numerical simulations using the Spectral Elements Method the two-dimensional the flow past a single circular cylinder that is either in simple harmonic cross-flow oscillation or elastically mounted. This is a very important topic for the technological environment because this configuration is identical to offshore structures, like risers of oil production platform and is also important to scientific environment due to the study of complex phenomena originated from the flow past a very simple geometry: a circular cylinder. The focus of this research is to evaluate the use of Spectral Element Method for solution of two-dimensional flow past a circular cylinder that is either in simple harmonic cross-flow oscillation or elastically mounted, at the laminar wake limit, Re
