Flow field around a prism with sway motion was experimentally investigated by wind tunnel experiment. The prism, which was made of the polyurethane block, was cantilevered on a flat plate. The swaying motion of the prism involves a flow induced in-line oscillation with small amplitude. PIV measurement was conducted to show the instantaneous and the phase-averaged flow structure around the swaying prism. We discussed differences in flow structure between the curved prism and the pliant prism.
