RESUMO

This research is involved with the development of a drag-coefficient correlation for nonspherical particles settling in purely viscous non-Newtonian fluids. The dynamic interaction term between fluids and particles was studied using both the dimensional analysis and a large number of experimental data covering the laminar, transitional and turbulent flow regime to obtain a generalized correlation for the determination of the settling velocity valid for particles on a sphericity (?fi?) range from 0.5 to 1. Unlike the previous published research in this area, this generalized correlation doesnot depend on a particular rheological model. (...continue)
