dc.descriptionAbstract: Prototype measurements include static and dynamic values of pressures due to flow in the 66- and 78-in.-diam Howell-Bunger valves and hoods and strain on one vane of each valve. Transverse, vertical, and peripheral accelerations were measured at the downstream end of the valve cone. Vertical accelerations were also measured on the upstream end of the hood of each valve. Data were recorded on analog magnetic tape and played back on oscillograph charts to verify the recording. Results of the data reduction include information on discharge characteristics of the New Melones valves, evaluation of the pressure fluctuations for flows in the valves and hoods, evaluation of the vibration of the valve and hood structures, and evaluation of the strain measurements on the test vanes. The significant amplitudes of accelerations on the FC&I valve were due to the dynamic flow control shift which was not evident in vibrations of the LL valve. The pressure fluctuations revealed that buffeting was more evident in the fully developed turbulent flow of the LL valve than that resulting from the upstream bifurcations in the FC&I conduit.-
