“…A simple power plant that can be applied to traditional fishing boats is the Archimedes screw turbine, this turbine is fish-friendly and also relatively inexpensive to manufacture [7]. One way that can be done to increase the efficiency of this turbine is to use pumped storage [8], in other words, take advantage of the water flow along with the speed of the ship.…”

“…Entre os ângulos ϕ 2 e ϕ 3 , considera-se que δH é constante e igual a (P/N ) sen (β). Essa aproximação produz resultados satisfatórios, entretanto alguns autores observaram que normalmente δH é variável ao longo do parafuso (DELLINGER et al, 2018;REIS;CARVALHO, 2018). Substituindo a Eq.…”

“…Fazendo essa substituição na Eq. (3.100), chega-se a equação proposta por Muysken (1932) para calcular o vazamento pelas frestas: RORRES, 2013;ROHMER et al, 2016;REIS;CARVALHO, 2018), entretanto sua desvantagem é necessitar de um coeficiente de descarga (µ A ) para ajustar a velocidade na fresta. No presente trabalho, propõe-se que a velocidade do escoamento na fresta seja calculada através de modelagem numérica.…”
