Abstract
In a marine application a two-cylinder configuration was used that created a bistable jet in the gap between the two cylinders. A literature search was performed to gain an understanding of the unsteady fluid dynamics leading to the observed violent structural response to this flow phenomenon. As no satisfactory explanation could be found in the available literature, a study was performed. It showed that such fluidelastic instability couls result from the coupling between flow separation and the motion of the tandem-cylinder configuration generated by moving-wall effects.
