Abstract

Two-dimensional simulations of flow past an elastically mounted cylinder, and flow past an externally driven oscillating cylinder were performed at a Reynolds number of 200. The results of both are compared to see if the driven oscillation could model the coupled fluid-structure flow of the elastically mounted cylinder. The driven system could model the elastically mounted system, but was very sensitive to input parameters. We argue that this sensitivity could cause experimental discrepancies between the two systems.
