Aplicação de técnicas de CFD no estudo da eficiência de estágio em colunas de destilação para produção de etanol
(Universidade Federal de São Carlos, 2014-03-17)
Distillation is one of the most important and used separation techniques of components at industrial level, applied in a wide range of processes. Its great importance is due to the capacity of purify components of a mixture ...
Aplicação da fluidodinâmica computacional (CFD) no estudo do escoamento de ar e deposição de partículas em vias aéreas pulmonares
(Universidade Federal de São Carlos, 2014-02-28)
The industrialization process and the fast growth of cities lead to an increase of respiratory diseases and, therefore, lead to the beginning of studies involving particle deposition in human lung airways. This work used ...
Aplicação de técnicas de Fluidodinâmica Computacional (CFD) na avaliação da hidrodinâmica e da transferência de massa em estágio de coluna de destilação
(Universidade Federal de São Carlos, 2015-02-19)
Distillation is one of the most important industrial separation techniques. It requires high quantity of energy, corresponding to around 40% of the total energy consumption of chemical industries. As such, the optimization ...
Reforma a vapor de butanol com catalisadores de Ni,Co/MgAl2O4: efeito da composição do catalisador (Ni,Co) e reagentes (H2,H2O,Butanol) nas rotas reacionais de reação
(Universidade Federal de São Carlos, 2016-04-29)
The effect of metal composition (Ni,Co) and the reactants composition (H2:H2O:Butanol) in the catalytic properties were studied for the Ni,Co/MgAl2O4 catalysts in the reaction of steam reforming of butanol (SRB) The catalysts ...
Estudo de um leito fixo de pequena espessura utilizando CFD
(Universidade Federal de São Carlos, 2016-03-07)
Studies carried out in fixed bed, a major experimental research equipment, use a simplified approach for assessing, for example, drying kinetics of various materials, known as thin-layer approach. For a given system can ...
Transferência de oxigênio e cisalhamento em biorreator convencional com diferentes combinações de impelidores
(Universidade Federal de São Carlos, 2016-02-26)
The type and operational conditions of a bioreactor chosen during the production phase of a product of interest affect not only the morphology and growth of filamentous microorganisms but also the product itself. Still the ...
