Modeling of the Mixing of Composite Solid Propellant Slurry in a Kneading Mixer

Abstract:

The mixing process of composite solid propellant slurry in kneading mixers is considered as the research object. POLYFLOW software is employed to solve the problems numerically. Turning the mixing tank instead of the revolution of the impellers, thus the planetary motion is carried out only by the autorotation of the impellers around their own axes. With mesh superposition technique and mesh refinement technique, the impellers and mixing tank are meshed. Visualization of flow process and flow pattern in a kneading mixer is realized and flow fields of velocity, shear stress, viscosity and mixing index are obtained.
