Large-Eddy Simulation of an Oscillating Cylinder in a Steady Flow
Artikel i vetenskaplig tidskrift, 2013

In this work, large-eddy simulation is used to study the flow around a circular cylinder undergoing streamwise sinusoidal oscillations. This benchmark case is a first step toward studying engineering applications related to flow-induced vibrations. Both the flow physics, which correlate the flow development with the time varying loading of the cylinder at two different oscillation frequencies, as well as a validation of the fluid structure interaction methodology through comparison with experimental data for the same configuration are described. With the methodology used, large-eddy simulation based on a finite volume method capable of handling moving meshes gives force predictions that generally agree well with experimentally measured data, both with respect to the overall flow development as with force magnitude.
