Flow Characteristics in Flood-Control Tunnel 10, Fort Randall Dam, Missouri River, South Dakota. Hydraulic Prototype Tests
Tests were conducted in tunnel 10 to investigate flow characteristics of a large circular tunnel, flowing full. Measurements included pressures in the tunnel intake and along the tunnel, and velocity distributions obtained from nine total-head tubes mounted on a streamlined strut spanning the tunnel horizontally. The strut instrumentation also included six pressure transducers and three hot-film anemometers. The electrical signals from the transducers and anemometers were recorded on both oscillographs and magnetic tape. Total-head tubes mounted on boundary zone probes were used to traverse the region of flow near the wall. Intake and transition pressures were generally lower than those measured in a previous model study of the tunnel. Resistance coefficients indicate an interior surface intermediate between hydraulically smooth and rough flow limits, but closer to rough. (Author)
