[en] GRANULAR SEGREGATION OF MIXTURES AS A DIFFUSION PROBLEM / [pt] SEGREGAÇÃO EM MISTURAS DE SISTEMAS GRANULARES COMO UM PROBLEMA DE DIFUSÃO

FELIPO LIVIO LEMOS LUZ 11 April 2005 (has links)
[pt] Neste trabalho estudamos o comportamento dinâmico de uma mistura binária granular submetida a uma equação do tipo Cahn-Hilliard com o objetivo de observar o fenômeno da segregação. Construímos um modelo de sistema de células dinâmicas para simularmos computacionalmente esses sistemas e observarmos o seu comportamento, a fim de comparar nosso modelo com o que é observado experimentalmente. / [en] In this work we study the dynamic behavior of a granular binary mixture with the aim of investigation phenomenom. We construct also a cell dynamic systems model to simulate computationally these systems and observe its behaviour, in order to compare our model with the experiments.
