A complementary numerical and physical investigation of vortex-induced vibration

Results are presented from low Reynolds number experimental investigations of vortex-induced vibration and comparison is made with results from corres ponding two- and three-dimensional direct numerical simulations. It is show n that three-dimensional simulations are required to reproduce the response envelope observed experimentally. Phase-averaged contours of spanwise vort icity demonstrate the presence of the 2P shedding mode on the lower respons e branch in both the experimental and three-dimensional simulation results.
