We investigate the aeroelastic behaviour of a slender U‐beam in cross‐flow. Two distinct, time periodic flow patterns are observed in simulations of the flow around this beam. Its aeroelastic properties depend on the realized flow pattern, especially so for low reduced velocities: One flow pattern leads to pronounced torsional vortex‐induced vibrations. No such vibrations could be observed under the other flow pattern. (© 2014 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
