Analysis of hydraulic parameters in determining the occurrence of cavitation in the spillways of the Furnas, Luiz Carlos Barreto de Carvalho and Batalha hydroelectric power plants
Abreu, Aline Saupe; Novakoski, Carolina Kuhn; Priebe, Priscila dos Santos; Trierweiler Neto, Edgar Fernando; Teixeira, Eder Daniel; Marques, Marcelo Giulian; Prá, Mauricio Dai (2024) [Artigo de periódico]The hydrodynamic conditions to which hydraulic structures such as spillways and stilling basins of dams are submitted under given conditions favor the occurrence of cavitation, damaging the concrete surfaces. This damage ... -
Experimental study of pressure flushing of non-cohesive sediment through slotted pipe bottom outlet
Paulo, Felipe Azevedo; Abreu, Aline Saupe; Prá, Mauricio Dai; Endres, Luiz Augusto Magalhães; Ferla, Rute; Teixeira, Eder Daniel (2021) [Artigo de periódico]Among several techniques for prevention and mitigation of reservoir sedimentation, bottom outlets arise as a means of removing sediment deposited close to the dam. Given the reduced sediment removal provided by traditional ... -
Induced aeration flow over stepped spillways: mean pressures, air entrainment and flow behavior
Novakoski, Carolina Kuhn; Ferla, Rute; Priebe, Priscila dos Santos; Abreu, Aline Saupe; Marques, Marcelo Giulian; Dai Prá, Maurício; Canellas, Alba Valéria Brandão; Teixeira, Eder Daniel (2021) [Artigo de periódico]Stepped spillways can dissipate a great amount of energy during the flow passage over the chute, however these structures have limited operation due to the risk of cavitation damage. The induced aeration may protect the ... -
Influence of aeration induced by piers on the starting position of the flow aeration and extreme pressures in stepped spillways
Priebe, Priscila dos Santos; Ferla, Rute; Novakoski, Carolina Kuhn; Abreu, Aline Saupe; Teixeira, Eder Daniel; Prá, Mauricio Dai; Marques, Marcelo Giulian (2021) [Artigo de periódico]The operation of stepped spillways is limited by a range of discharges due to the risk of occurrence of the cavitation phenomenon and erosion on its steps. Since there is a demand for spillways with the possibility of ...
