Estudo Experimental das Características do Escoamento em Escadas para Peixes do Tipo Ranhura Vertical — Padrões Gerais do Escoamento

Abstract: A construção de barramentos ao longo dos rios causa muitas alterações no meio envolvido. Entre esses impactos, tem-se a formação de uma barreira que impede o deslocamento do habitat aquático, interferindo, principalmente, na reprodução das espécies migratórias. Na tentativa de mitigar esse efeito, em muitas barragens, verifica-se a necessidade da implantação de mecanismos de transposição de peixes (MTP). Entre esses MTP têm-se as escadas para peixes que, quando empregadas e projetadas adequadamente, possibilit… Show more

“…Numerical flow simulations were performed for three discharge rates: 0.02159 m 3 /s, 0.02451 m 3 /s and 0.02916 m 3 /s, which are the same flow rates evaluated experimentally by Sanagiotto et al (2011Sanagiotto et al ( , 2012. These discharges correspond to prototype flow rates of 1.21 m 3 /s, 1.37 m 3 /s and 1.63 m 3 /s, respectively.…”

“…The focus of this work is the vertical slot fishway installed at Igarapava Hydropower Plant (HPP) in Brazil, described by Viana, Martinez and Marques (2007) and Viana, Faria and Martinez (2014). Prior studies have presented results on the behavior of the flow in this structure, obtained through a partial physical model at a 1:5 scale (SANAGIOTTO et al, 2012(SANAGIOTTO et al, , 2011. In this work, we validate a 3D computational fluid dynamic model for analysis of vertical slot fishways.…”
