Force measurements on bluff cylinders and aeroelastic galloping of a rectangular cylinder Santosham, Thomas V.

Abstract

Dynamic wind tunnel tests were made on plunging rectangular 2:1 and 1/2:1 cylinders and the results were compared with predictions of a quasi-steady theory. The velocity-amplitude and time-amplitude curves for those cylinders which oscillated were recorded. Dynamic tests were also performed on a 2:1 rectangular cylinder with a 10" splitter plate mounted on the wake centerline to prevent the vortex excitation. Direct static force measurements for the Reynolds number range 2 x 10⁴
