Determinação experimental de parâmetros de interação e aplicação na simulação CFD-DEM de leito de jorro
(Universidade Federal de São Carlos, 2020-02-19)
Spouted beds feature the intense mixture of solids, which favors the mechanisms of heat and mass transfer. The understanding of these phenomena is associated with the difficult to obtain details of fluid dynamics by the ...
Fluidodinâmica e transferência de calor em leitos de jorro visando a secagem de grãos de Sorgo: análise experimental e simulação numérica por CFD-DEM e TFM
(Universidade Federal de São Carlos, 2021-04-23)
Simulations of granular flows in spouted beds are carried out following two main approaches: two-fluid model (TFM) and CFD-DEM coupling (Computational Fluid Dynamics/Discrete Element Method). Moreover, the fluid dynamics ...
Estudo sobre o desempenho de válvulas não-mecânicas como alimentadores de biomassa residual de borra de café em reatores de leito pneumático circulante: experimentação e modelagem via CFD-TFM
(Universidade Federal de São Carlos, 2020-08-24)
The continuous and stable feeding of particulate solids to reactors is essential for energy cogeneration in industrial processes, for example, by using biomass residues. Nevertheless, flow instabilities and blockage of ...
Análise de diferentes configurações do leito de jorro com agitador mecânico e do equipamento convencional
(Universidade Federal de São Carlos, 2022-03-24)
The mechanical spouted bed emerged as a modification of the conventional spouted bed
to minimize problems in the movement of solids and the need for high air flows just for
the existence of the spouting regimen. Therefore, ...
Intermittent drying and draft tube design for spouted bed
(Universidade Federal de São Carlos, 2021-12-08)
The conventional spouted bed has presented several limitations that restrict the use on an industrial scale. Thus, studies of different methodologies and configurations have been performed to overcome such limitations. ...
