Modelagem matemática aplicada ao estudo de células a combustível a etanol direto
(Universidade Federal de São Carlos, 2022-03-09)
The current fuel cell market is dominated by Hydrogen cells. Nevertheless, due to Hydrogen’s high reactivity, the difficulty in storage and the lack of infrastructure to distribute it, Hydrogen cells might not be the most ...
Borra de café: análise da caracterização termoquímica, do processo de elutriação, secagem, peletização e da mistura com outros resíduos
(Universidade Federal de São Carlos, 2023-04-27)
For the reuse of the spent coffee grounds, this thesis has two main strategies, the first is to evaluate its granulometry as a function of the thermal degradation behavior, the elutriation, drying process, pelletization ...
Desenvolvimento e estudo da influência de um modelo de força de lubrificação em um leito fluidizado líquido utilizando CFD-DEM não resolvido
(Universidade Federal de São Carlos, 2023-02-28)
Solid-fluid multiphase flows are common occurrences in chemical engineering applications. Due to the scale and unpredictability of the fundamental phenomena in these systems, microscopic interactions between individual ...
Secagem convectiva de concentrado de minério de ferro: abordagem experimental e simulações por fluidodinâmica computacional
(Universidade Federal de São Carlos, 2023-02-27)
Conventional transfer chutes are equipment used to change the solids flow direction in transporting systems that use conveyor belts. During operation, the solid transported by the upper conveyor belt enters the chute and ...
