Estudo hidrodinâmico computacional de reator uasb em escala de laboratório

Abstract

O objetivo do presente trabalho foi avaliar o comportamento hidrodinâmico de um reator UASB de 18 L por meio da fluidodinâmica computacional (CFD) e de ensaios do tipo estímulo-resposta experimentais. Foram realizadas simulações computacionais do comportamento hidrodinâmico do reator operando com a injeção de ar na região da manta de lodo (1º etapa). Foi realizada também a simulação de operação do reator com o preenchimento de 35% do seu volume útil com um polímero absorvente de água abiótico (2ª etapa). O modelo computacional utilizado para a simulação do reator em escala de bancada foi validado por meio da comparação do volume de zonas mortas obtido por meio das simulações com os valores calculados nos ensaios de estímulo-resposta com o traçador Eosina Y. O volume de zonas mortas calculadas por meio dos ensaios apresentou um erro de aproximadamente 43% em relação ao valor obtido com o modelo computacional do reator para a 1ª etapa, validando os resultados da simulação. Palavras-chave: Fluidodinâmica computacional. Ansys CFX. Traçador. Difusão. Anomalias.
