摘要：
The mixing and clarifying tank is an important extraction and separation equipment. In this study, computational fluid dynamics (CFD) method was used to study the fluid flow and shear force in a new type of axial flow pump type mixer (AFPM). The impact of the impeller type on average shear rate, spatial distribution of shear rate, and probability distribution of shear rate in the mixing chamber was analyzed. The results demonstrate that the combination of the conical pump and double blade yields significantly improved suction and shear force compared to traditional mixers. Furthermore, the six-bladed semi-closed turbine (SBSCT) blade can increase suction force by 87% and average shear rate by 90%. The axial flow pump also provides a more evenly distributed shear force within the mixing chamber. © 2024 Materials China. All rights reserved.
