Abstract

Patente de Invenção: "MéTODO E SISTEMA PRETENDIDO PARA UMA ESTIMATIVA EM TEMPO REAL DO MODO DE ESCOAMENTO DE UM FLUXO DE FLUIDO DE FASE MúLTIPLA EM TODOS OS PONTOS DE UMA TUBULAçãO". Método e sistema pretendidos para uma estimativa em tempo real do modo de escoamento, em todos os pontos de um tubo cuja estrutura é definida por um certo número de parâmetros estruturais, de um fluxo de fluido de fase múltipla definido por várias quantidades físicas. Uma rede neural não-linear é formada com uma camada de entrada tendo tantas entradas quantos forem os parâmetros estruturais e as quantidades físicas, uma camada de saída com tantas saídas quantas forem as quantidades necessárias para a estimativa do modo de escoamento e pelo menos uma camada intermediária. Uma base de aprendizado é criada, com tabelas predeterminadas conectando vários valores obtidos para os dados de saída aos valores correspondentes dos dados de entrada, com uma determinação iterativa dos fatores de ponderação da função de ativação, permitindo conectar, apropriadamente, os valores nas tabelas de dados de entrada e de saída. De modo a evitar que singularidades dos dados de saída da rede, provavelmente, distorçam a determinação dos fatores de ponderação, um procedimento de classificação é usado, para a eliminação dos dados não-pertinentes. As vantagens principais do método são: simplificação da modelagem e economia de tempo. Aplicações: implementação simplificada de módulos hidrodinâmicos, que podem ser integrados nas ferramentas de modelagem, por exemplo.
