Abstract

This paper presents a numerical study on the dynamic behavior of a flexible plate located behind a cylinder and confined between two parallel walls. This two-dimensional fluid-structure interaction problem was performed for four different cylinder sizes, with focus on blockage effects. The oscillation amplitude and frequency of the plate tip were examined as affected by the cylinder size and blockage ratio (ratio of the cylinder diameter to the channel width) which varied from 0.05 to 0.49. The oscillation amplitude and frequency of the plate tip is strongly affected by the combined effects of blockage and cylinder size. The results suggest that the dynamic behaviour of the plate may be altered by varying blockage and cylinder size.
