Characterization of Bead Trajectories Through the Draft Tube of a Turbine Physical Model.
Abstract
Using high-speed video imaging, trajectories, and kinematics of beads passing below the turbine runner and through the draft tube region of the 1:25 scale model of a single turbine unit from Bonneville Dam powerhouse 1 were collected from May 6-9, 2003 at U.S. Army Corps of Engineers (USACE) Environmental Research and Development Center (ERDC) in Vicksburg, MS. An individual camera was used to produce 2-dimensional trajectories and paired cameras with overlapping fields of view were used to produce 3-dimension trajectories of near neutrally buoyant beads as they passed through the draft tube region of the turbine model. Image data was collected at two turbine operating levels, lower 1% efficiency and maximum rated output for beads released mid-depth into the turbine intake from each of the three gatewell slots. The purpose of this study was to determine the feasibility of using video imaging to track the trajectories of beads through the draft tube of turbine physical models and from the trajectories calculate the kinematics of the bead trajectory and the beads response to turbulence in the model. This project is part of a research program supported by the U.S. Department of Energy Advanced Hydropower Turbine System Program (AHTS) who's goal ismore »
