Abstract
This paper presents phase-resolved Particle-Image Velocimetry measurements on fluid-structure interactions in a water channel, performed at a Reynolds number of 30,470. The structure model consists of a fixed rigid cylinder with a deformable polymer plate behind it and is implemented into a vertical closed circuit tunnel at inlet velocities of 1.38 m/s. Phase-resolved measurements triggered by a precise laser distance sensor were performed to capture averaged velocity fields at several moments of the structure deflection, enabling comparisons to numerical fluid-structure interaction simulations currently under investigation.
