Abstract
The present study spearheads an ongoing effort aimed at develo** a computationally inexpensive and reasonably accurate numerical simulation model for the prediction of the material removal distribution over the surfaces of additively manufactured parts polished by the stream finishing process. To this end, the parameters of a continuum-based granular flow dynamics model are calibrated against experimental data obtained by interrogating the media flow field, in a typical stream finishing drum, with a purpose-designed probe. Interestingly, it was observed that, including a shear stress and pressure dependent wall-slip wall model yielded a better comparison with the experimental data; whilst, the prognosis is that a free-slip condition appears adequate as a first approximation.
