FLUID-INDUCED LOADING OF CANTILEVERED CIRCULAR-CYLINDERS IN A LOW-TURBULENCE UNIFORM-FLOW .2. FLUCTUATING LOADS ON A CANTILEVER OF ASPECT RATIO-30

Part 2 presents details of an investigation into the fluctuating loads induced on a smooth, cantilevered circular cylinder with an aspect ratio of 30 immersed in a low-turbulence uniform flow. Experiments were carried out in a wind tunnel at a Reynolds number of 4·4 × 104 and involved the measurement of fluctuating pressures and forces. Oil-flow visualization was performed to determine the flow pattern at the surface of the cylinder. The results reveal the nature of the disturbance induced by the flow around the free-end of a cantilever and the full extent of the spanwise variation of fluctuating pressures and forces. © 1993 by Academic Press, Inc.
