Abstract:
Accumulation of debris in hydropower plants is an important concern to be addressed in order to avoid the reduction in the plant efficiency. This phenomenon can be mitigated by the usage of debris booms, which are floating structures installed in the river used to contain and deflect these debris. Large logs associated with the high water flow velocities are the present elements in the Madeira River, more specifically at the Santo Antônio hydropower plant. Being a non-trivial incident, the usage of experimental techniques is recommended to better understand the dynamics of the log booms and verify numerical and analytical models. This paper develops a structural analysis for a truncated 1:10 scale model of a containment structure that is towed in the model basin of the Institute for Technological Research. It presents the methodology used for design the experimental setup, the manufacturing project and test considerations of the scale model, the instrumentation adopted to measure the local strains and total forces, and the data reduction on the conduced tests. The developed methodology is part of an R & D project requested by Santo Antônio Energia and developed by IPT.
