Artigo:

In the present work, some fluid-dynamics aspects of a rotary drum, operating with acerola residue particles were investigated experimentally and by DE Discret Elements Method (DEM). In order to evaluate the effect of parameters of the JKR contact force model on the dynamic angle of repose, a central composite design was used to plan the DEM simulations, performed by EDEM software. The simulated dynamic angles of repose were compared with the experimental one and it were selected the parameters the better represent the fluid dynamic behavior of the acerola residue particles.
