MOVING WALL EFFECTS CAUSING FLUIDELASTIC INSTABILITY

In a marine application a two-cylinder configuration was used that cre ated a bistable jet in the gap between the two cylinders. A literature search was performed to gain an understanding of the unsteady fluid d ynamics leading to the observed violent structural response to this fl ow phenomenon. As no satisfactory explanation could be found in the av ailable literature, a study was performed. It showed that such fluidel astic instability could result from the coupling between flow separati on and the motion of the tandem-cylinder configuration generated by mo ving-wall effects.
