In the crystallization process, the quality of crystal formation is signifi cantly aff ected by the stirring mechanism. Typically,

the effi ciency of mixing is directly correlated with the rotational speed of the stirrer. Nevertheless, elevated stirring speeds

can lead to the fragmentation of crystal nuclei, thereby exerting a detrimental infl uence on the overall crystallization quality.

To address such issue, a glass-lined V-shaped stirrer with a better stirring eff ect under low-speed conditions was developed in

the present study. Particular attention was paid to providing a better stirring eff ect under low-speed conditions. The computational

fl uid dynamics (CFD) numerical simulation method was employed to conduct a comparative analysis of the fl ow fi eld

distribution when subjected to the infl uence of a V-shaped stirrer in comparison with two frequently employed stirrers. The

velocity fi eld, turbulence intensity, particle distribution and heat transfer rate were analyzed, and experimental measurements

of the mixing time were conducted. The fi ndings from the present study reveal that when the stirring paddle was operated

at a speed of 80 rpm, the V-shaped stirrer exhibited a larger circulation range compared with the other two stirrers. Further,

the overall turbulence intensity in the fl ow fi eld was higher, ensuring a more homogeneous distribution of crystal nuclei.

Additionally, the heat transfer rate was found to be signifi cantly faster, contributing to improved crystallization effi ciency and

higher-quality crystallization products. The utilization of the glass-lined V-shaped stirrer off ers the advantage of improved

mixing effi ciency in the crystallization process, while maintaining the crystal quality. This innovation has the potential to

bring about a transformative shift in manufacturing processes and contribute to advancements in the fi eld of crystallization.
