| Description: | Contract Report From the Introduction: Abrupt spatial changes in boundary form are common features in many hydraulic structures. Considerable attention has been focused on those cases in which a free shear layer is present in the flow field, since distressing and sometimes catastrophic flow-induced vibrations have resulted from the interaction of the free-shear layer and the structure. Practical examples involving flow-induced vibration include the singing of turbine blades and ship propellers, the galloping of power transmission lines, the buffetting of one of a row of smokestacks, and the vibration of high-head gates in dams and outlet works. Although these illustrations seem unrelated, one factor is common to all: a free shear layer is associated with the flow in each case, and is one of the primary factors in providing a means by which basic flow instabilities ultimately manifest themselves as flow-induced structural vibrations. The last example, high-head gates in dams and outlet works, has been the principal concern of the present investigation. NOTE: This file is large.
