Secagem de pêra em secador a microondas
(Universidade Federal de São Carlos, 2003-08-05)
The present work has as main objective the pear drying in three different dryers: convective, microwave and microwave-convective. It is also intended to evaluate the effect of the osmotic dehydration, as pré-treatment, in ...
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 ...
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 ...
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 ...
