Title in Portuguese
Análise bidimensional de interação fluido-estrutura: desenvolvimento de código computacional
Keywords in Portuguese
dinâmica dos fluidos computacional
interação fluido estrutura
método dos elementos finitos
não linearidade geométrica
Abstract in Portuguese
O presente trabalho consiste no desenvolvimento de um código computacional baseado no método dos elementos finitos (MEF), para análise bidimensional de interação fluido-estrutura. Desenvolve-se um código bidimensional para dinâmica de fluidos compressíveis, viscosos ou não, em formulação Euleriana, com base no algoritmo CBS – characteristic based split. Então o código desenvolvido é adaptado para poder ser acoplado a um programa de formulação Lagrangeana para análise dinâmica de estruturas, o que é feito através do emprego da descrição Lagrangeana - Euleriana arbitrária (ALE). Por fim procede-se o acoplamento com um código para análise de estruturas, de formulação posicional e não linear geométrica, baseado no método dos elementos finitos.

Abstract in English
The present work consists of the development of a computational code based on the element finite method for fluid-structure interaction analysis. A two-dimensional fluid dynamic Eulerian code is developed based on the CBS algorithm – characteristic based split. Then, the computational code is modified to be coupled with a Lagrangean structures dynamical code by using the arbitrary Lagrangean – Eulerian description (ALE). At the end, the coupling is made with a positional nonlinear geometrical structural dynamics code based on the finite element method.
