Dynamic pressure analysis at chute flip buckets of five dam model studies

To dissipate energy and invert excessive discharge flow away from high dams into plunge pool, flip buckets are commonly designed and optimized by hydraulic model studies. in the present study, performance of chute flip buckets in different hydraulic and geometry conditions was investigated using experimental data of five different physical models. the collected experimental data such as froude number, radius of flip bucket and slope of chute covered a wide range of chute flip buckets in prototype. by analyzing the data, relations for dynamic values of maximum and minimum pressures and their location along the flip bucket were extracted. moreover, pressure distribution along the central axis of flip bucket was defined. finally, results of the present research were compared with that of the other researches. results of this study could be used in the design of chute flip buckets in hydraulic engineering.
