Estudo do mecanismo eletroforético de coleta na filtração de aerossóis
(Universidade Federal de São Carlos, 2007-05-18)
Previous works have shown that the presence of electrostatic forces in particles significantly affect the performance of a filter, both increasing collection efficiency and reducing pressure drop. Recently, in the Environmental ...
Filtração de gases: estudo da deposição de diferentes tortas de filtração em diferentes meios filtrantes
(Universidade Federal de São Carlos, 2006-06-19)
The particle retention inside a filter medium, after cleaning, significantly improves the
initial pressure drop during the subsequent cycle, that is, the residual pressure drop.
However, the way as these particles ...
Estudo da fluidodinâmica em leito fixo utilizando-se métodos numéricos de solução: escoamento monofásico de ar
(Universidade Federal de São Carlos, 2006-03-09)
Studies accomplished in the structure of tubular fixed beds proved that the porosity in these systems presents an oscillatory behavior along the radial direction. The non-uniformity of the porosity generates a behavior of ...
Contribuições ao estudo da secagem em um leito pneumático vertical
(Universidade Federal de São Carlos, 2004-03-30)
Pneumatic dryers are widely applied in industry, mainly because the transport of particulate material can be performed simultaneously with heating and drying operations. However, the design of such equipment is still based ...
Estudo do comportamento da deposição das partículas de diferentes meios filtrantes
(Universidade Federal de São Carlos, 2008-03-17)
Many studies related to bag filters have focused on minimizing the amount of energy used in the process. Seeking longer filtration cycles, lower frequency of cleaning cycles and a longer filter life, such studies search ...
Influência do alimentador de sólidos na fluidodinâmica do transporte pneumático
(Universidade Federal de São Carlos, 2007-03-13)
Pneumatic transport is an operation where powdery and granular materials are conveyed through a pipeline suspended in a gas flow. It is usually found in several industries segments and it is used as a carrier, such as, in ...
Análise do comportamento da fluidodinâmica do leito de jorro com misturas de tamanho de partículas
(Universidade Federal de São Carlos, 2006-08-01)
This research study presents an investigation to quantify the stability
of spouting regimes (by pressure fluctuations) and particle segregation level in
conical spouted beds operated with a variety of particle combinations ...
Catalisadores de Mo suportados sobre sílica, sílica-titânia ou sílica-zircônia promovidos por Co ou Ni: avaliação do método de preparação e da composição do suporte na atividade para HDS
(Universidade Federal de São Carlos, 2012-04-30)
Hydrodesulfurization (HDS) catalysts containing Mo, NiMo or CoMo were supported on silica, silica-titania and silica-zirconia. These supports were synthesized by the sol-gel method, using citric acid as an agent to pore ...
Secagem convectiva de folhas de hortelã: análise baseada no ajuste de correlações empíricas, superfícies de respostas e redes neurais
(Universidade Federal de São Carlos, 2013-03-15)
Mentha x villosa H. is a species of mint popularly known as regular mint. Besides being widely used as a spice, their leaves yield an essential oil with many healthy compounds that are commonly used in formulation of ...
Quantificação de apoptose e necrose mediante corantes fluorescentes e análise de imagens, no cultivo de células de inseto: o caso da Drosophila melanogaster S2
(Universidade Federal de São Carlos, 2007-03-28)
In animal cell cultures there are two kinds of cell death: apoptosis
(programmed cell death) and necrosis (cell death due to external sources). The inovative
method of cell death identification that have attracted interest ...
