Modelagem e simulação dinâmica de reatores de leito fixo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2011-02-25)
This work investigated numerical methods in the solution of mathematical models of fixed-bed reactors. For the reactors modeling and simulation, two numerical methods were used: sequencing method (SM) and finite volume ...
Simulação numérica de trocadores de calor multitubulares equipados com fitas helicoidais externamente aos tubos
(1998-03-01)
Classical shell-and-tube heat exchangers are usually equipped with segmental baffles. These baffles serve two basic functions: (a) they provide tube supports, thereby preventing or reducing mechanical problems, such as ...

Numeric simulation of pollutant dispersion by a control-volume based on finite element method
(Wiley-Blackwell, 2011-07-30)
The dispersion of pollutants in the environment is an issue of great interest as it directly affects air quality, mainly in large cities. Experimental and numerical tools have been used to predict the behavior of pollutant ...
