RESUMO

In the developed work was studied the forces which act on a particle when these is a moving inside of a flow, in order to find out a methodology which is able to represent the particle dynamics on a flow. The equation of particle motion was integrated with a numerical approach taking in account the apparent mass, static drag, dynamic drag (history term; Boussinesq/Basset force) and lift force; Magnus effect and Saffman effect. The finite volume method was used to simulate the flow. In the force analyses we used experimental and numerical simulation (FLUENT) to evaluate and extend the models shown on the review. FLUENT was validated to determine the static drag coefficient and lift coefficient due to Magnus effect.
