Abstract in Portuguese
Um problema relevante na modelagem de escoamentos com movimento de corpo rígido consiste na consideração de forças externas bem como forças que o fluido exerce sobre o próprio corpo rígido. Um outro problema importante refere-se à descrição da trajetória dos corpos rígidos. Essas duas questões são o objeto de estudo deste trabalho. No sentido de solucioná-las, foram implementadas duas extensões ao modelador de movimentos do sistema Freeflow-3D. A primeira incorpora um tipo de movimento definido por forças externas e a segunda um tipo de movimento definido por interpolação linear por partes.

Abstract in English
A relevant problem in the modeling of the flow of fluids with rigid body movements consists in the consideration of externai forces, as well as forces that the fluids apply in the rigid body. Another important problem in this domain refers to the description of the path of the rigid bodies. Studying these two issues was the goal of this work. Towards solving these problems, two extensions were implemented in the movement modeler of the Freeflow-3D system. The first one, adds to the modeler a new type of movement, defined by externai forces. The second, adds another type of movement defined by piecewise linear interpolation.
