Numerical Characterization of Mixing in a Kneading Element Channel of Dual-Speed Corotating Non-Twin Screws Using Lagrangian Statistics Method

Abstract

Front Cover: Symmetry break is introduced by a novel non-twin kneading element. The self-cleaning still remains where one-tip rotor engaged with two-tip one replaces two identical two-tip rotors of conventional twin screws. The numerical simulation is performed using finite element method and mesh superposition technique. A Lagrangian statistics method reveals that the non-twin geometry offers equivalent distributive mixing and better dispersive mixing. This is reported by Baiping Xu, Ruifeng Liang, Shuping Xiao, Lingcao Tan, Jian Song, and Huiwen Yu in article number 2200052.
