Abstract

An analysis is presented of mixing in cavity flows and in the single-screw extruder, valid for realistic degrees of mixing (stretching). The limitations of conventional numerical tracking schemes and the general characteristics of flows with weak reorientation are discussed. The analysis gives insight into the physics of the process and suggests ways for improved operation by highlighting the role of operating conditions, the mode of feed introduction, and the role of mixing sections.
