Abstract

Results are presented from low Reynolds number experimental investigations of vortex-induced vibration and comparison is made with results from corresponding two- and three-dimensional direct numerical simulations. It is shown that three-dimensional simulations are required to reproduce the response envelope observed experimentally. Phase-averaged contours of span-wise vorticity demonstrate the presence of the 2P shedding mode on the lower response branch in both the experimental and three-dimensional simulation results.
