Abstract
An experimental study was conducted for the fluid–structure interaction (FSI) of the vibration of a flexible structure inside the channel driven cavity flow (CDCF). The structure was a thin flat plate whose one edge was clamped at the bottom of the three-dimensional CDCF system. Both aluminum and composite plates were examined. Initially the vibrational characteristics of the structures were measured without fluid flow. Subsequently, each structural vibration was measured under various flow rates through the CDCF system. The structural vibration was measured using strain gages attached to the structures as well as non-contact displacement sensors. Time histories of the strains and displacements were obtained, and their time averages and the vibrational magnitudes were computed as a function of the nominal flow rate through the channel cross-section. This set of test data is expected to be useful for validation of a computer program for analyzing a FSI problem.
