Process Simulation of Anchor Stirring in Crystallizer

Abstract:

The paper studies the mixing effects of anchor stirring on crystallization hybrid process. The single phase flow field of three dimensional in crystallizer of 5 L is simulated by the software of Star CCM+. The change of flow field is analyzed under different stirring speed in ammonium chloride solution. The simulation research shows that the speed of fluid in the area around impeller is high, but in the surrounding and bottom area of stirring shaft is low after forming a relatively stable flow field in the crystallizer. As the stirring speed enhancement, the speed of fluid in the surrounding area of impeller and velocity gradient increase too. However, the flow of fluid in the area of axial direction is not sufficient.
