Improving Mixing by Changing Topology Through Intermeshed Perturbation Rings in A Co-Rotating Non-Twin Screw Channel

Abstract

Front Cover: A repetitive topology of splitting and recombination is introduced into the flow channel of a dual-speed non-twin screws with the speed ratio of 2. A new kind of perturbation ring elements is proposed to achieve the above purpose. The mixing is numerically characterized in terms of evolution of tracer particles, mixing variance index and residence time distribution. This is reported by Baiping Xu, Ruifeng Liang, Shuping Xiao, Yanhong Feng, and Huiwen Yu in article number 2300048.
