This paper deals with an experimental study of flow-induced wave generated on a thin film under shear loading. The experiment is carried out to investigate the deformed shape of the thin film with various values of shear loading, and the wave propagation due to the interaction of the corrugated shape of the corrugation with the fluid flow in the narrow passage. As a result, it is clarified that the flow-induced wave occurs to the thin film caused by interaction of the corrugated shape of the corrugation due to the shear loading with the fluid flow in the narrow passage. Moreover, it is clarified that the traveling direction of the flow- induced wave is determined by the corrugated shape of the corrugation and fluid flow direction. The flow-induced wave propagates diagonally, almost across the fluid flow direction.
