Simulação da etapa de desbaste por elementos finitos na laminação de longos
(Universidade Federal de Minas GeraisUFMG, 2010-07-21)
Technology investments to increase productivity and product quality has long been the focus of studies by companies given the high competitiveness. High surface and internal quality to the wire rods and bars is essential ...
Indentation and scratching of iron by a rotating tool-a molecular dynamics study
(ELSEVIER, 2021-06-15)
When abrasive particles interact with a surface, besides translational center-of-mass motion also rotational motion of the abrasive may be involved. We perform molecular dynamics simulations of the influence of the rotational ...
Modelagem experimental e computacional DEM-CFD da fluidização de partículas Geldart-D com formato irregular
(Universidade do Vale do Rio dos Sinos, 2019-04-12)
Fluidized bed reactors find many applications in thermo-energy conversion processes. The preference for this type of system is due to the characteristics of high heat transfer and mass transfer rates between the particulate ...
