Modelagem computacional de ventosas automáticas de duplo efeito com abertura e fechamento não instantâneos

Abstract

Durante fenômenos transitórios podem ocorrer pressões muito baixas nos trechos mais elevados de uma tubulação, ocorrendo o acúmulo de ar que é arrastado pela água ocasionando sérios danos ao sistema. Os dispositivos mais utilizados para o alívio do transiente hidráulico (golpe de aríete) trabalham com ar, dentre eles, os mais utilizados são as ventosas automáticas, foco deste estudo. Neste trabalho foram feitas simulações do transiente hidráulico para verificar a eficiência das ventosas automáticas de abertura e fechamento não instantâneos como mecanismos para aliviar o golpe de aríete. As simulações foram realizadas utilizando o software UFC6 desenvolvido no Laboratório de Hidráulica Computacional (LHC) da UFC.
