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 ... -
Analysis of the longitudinal distribution of pressures near the ends of the vertical and horizontal faces in stepped spillway of slope 1V: 0.75H
Teixeira, Eder Daniel; Marques, Marcelo Giulian; Osmar, Fabrício Machado; Canellas, Alba Valéria Brandão; Saraiva, Lorena Silva; Priebe, Priscila dos Santos (2018) [Artigo de periódico]Stepped spillways have been widely used for flood runoff due to of their constructive advantages and in regards to energy dissipation during the drop, allowing downstream dissipation structures to be designed in smaller ... -
Avaliação das Flutuações de Pressão em Ressalto Hidráulico pela Dissociação de Esforços
Prá, Mauricio Dai; Teixeira, Eder Daniel; Marques, Marcelo Giulian; Priebe, Priscila dos Santos (2016) [Artigo de periódico]O ressalto hidráulico é um fenômeno muito utilizado para dissipar energia a jusante de estruturas hidráulicas em virtude das suas características bifásicas e macroturbulentas, associadas a intensas flutuações de pressão, ... -
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 ... -
Stepped spillways with aerators : hydrodynamic pressures and air entrainment
Ferla, Rute; Novakoski, Carolina Kuhn; Priebe, Priscila dos Santos; Prá, Mauricio Dai; Teixeira, Eder Daniel; Marques, Marcelo Giulian (2021) [Artigo de periódico]The possibility of damage due to the phenomenon of cavitation leads the design of stepped spillways considering maximum specific discharges of 15 to 30 m2/s, a limit considerably lower than that practiced on smooth chutes. ...
