Abstract

This paper describes experimental and analytical study on the behavior of a falling water sheet. The observation of water sheet displacement and air pressure variation in the chamber implies that one of the causes of oscillation is downward squeeze action of a water sheet on an air chamber. We propose a simplified analytical model. Analytical results agree well with experimental ones. Further analytical results explain the occurrence of multiple modes of oscillation in a condition. In addition, we explain the instability mechanism using the work done by a falling water sheet on an enclosed chamber.
