An experimental setup was developed for channel driven cavity flow in order to study the fluid-structure interaction and provide benchmark data for validation of numerical fluid-structure interaction models. The channel driven cavity flow is a modification from lid-driven cavity flow. To examine the fluid-structure interaction, the bottom side of the cavity is a deformable flat plate. All other boundaries are rigid. The fluid-structure interaction inside the cavity is driven by flow through a thin channel topside of the cavity. Water is used as the fluid. Fluid-structure interaction for different deformable plates during constant flow is quantified using a variety of strain and displacement measurement techniques. To establish suitable boundary conditions for numerical analysis of the experiment, the inlet velocity of the channel driven cavity flow is known. Outlet pressure is constant atmospheric. Numerical results are obtained using ANSYS's CFX and structure analysis.
