Abstract
A numerical investigation into the flow past curved cylinders at Reynolds numbers of 100 and 500 has been performed. Two different configurations of a quarter turn with the free-stream flow vector parallel to the plane of curvature have been simulated. The vortex shedding patterns and the wake topology are studied and the sectional forces at different locations of the span are presented. The three-dimensional simulations were computed with a spectral/hp element method and the computational results were compared with flow visualisation experiments undertaken in the towing tank facility of the Department of Aeronautics of Imperial College.
