Neste artigo é apresentado o desenvolvimento de um modelo dinâmico simplificado para um sistema encanamento-riser-separador sob regime de fluxo com golfadas. Esse tipo de escoamento caracteriza-se por fluxo severo e irregular com oscilações de pressão e vazão na tubulação e nas unidades de separação em indústrias de produção de petróleo. O modelo obtido é resultado do acoplamento entre o modelo dinâmico simplificado para o sistema encanamento-riser sujeito ao regimede fluxo com golfadas, e o modelo de um separador cilíndrico horizontal bifásico. São apresentados os resultados das simulações e observa-se que o modelo proposto representa de forma satisfatória a dinâmica da golfada no sistema encanamento riser, bem como dentro do separador.References
