Abstract

The blade free planetary mixer is a mixing process known since the 70's for its effectiveness in mixing quickly and without contamination viscous fluids (e.g.: alginate pastes, resins for polymerization's operations). Despite a great potential of applications, the blade free planetary mixer still unknown at the industry level and only few studies is available on its physical mechanism. Therefore, its optimization tends to be difficult. This thesis describes the hydrodynamic behaviour inside the blade free planetary mixer by modeling the flow and the mixing time for a homogeneous fluid by using computational fluid dynamics (CFD). In collaboration with the company G-Explore, it was possible to validate experimentally our CFD model on real mixer platforms with, among other, power and mixing time data. Moreover, we determined by a parametric study the configurations and the operating conditions that offer the lowest mixing time and/or the lowest cost for a specifie mixing quality criterion.
