Nonlinear constrained optimization with flexible tolerance method: improvement and application in systems synthesis of mass integration
(Universidade Federal de São Carlos, 2015-03-13)
Este trabalho visa a otimização não-linear restrita usando o Método das Tolerâncias Flexíveis (FTM) e na aplicação do mesmo na síntese de sistemas de integração mássica. A integração mássica é uma técnica que permite a ...
Modelagem da eficiência de coleta em ciclones utilizando a fluidodinâmica computacional
(Universidade Federal de São Carlos, 2013-09-30)
Cyclones are used to separate suspended particles from gas streams. The analysis of flow inside the cyclone is complex due to the large number of parameters and operating variables that influence the dynamics of the system. ...
Monitoramento em tempo real e simulação de controle da umidade de pós produzidos pela secagem de pastas em leito de jorro
(Universidade Federal de São Carlos, 2015-03-31)
The direct control of the product moisture content in dryers would be more interesting. However, as it happens with other processes, it is a concentration control, which is commonly dependent on slow or expensive procedures ...
