Resumo

The fluid flow over a particle bed model was solved using Large Eddy Simulation (LES) to better predict the turbulent structures development. Q and Ω criterions were used to identify turbulent structures development in the pos-processing. The results showed that LES is a very good methodology to access the fluid flow details. Besides, Ω-criterion showed to be a lower search cost option. Burst formations and its detachment from the surface can be associated to a particle emission event.
