文摘
- •
Primary nucleation in cooling dual impinging jet (DIJ) mixers is analyzed.
- •
The DIJ mixers generate supersaturation by combining hot and cold liquid solutions.
- •
Spatial distributions are derived for temperature and supersaturation.
- •
High local supersaturation can occur near the interface of hot and cold solutions.
- •
Criteria are given for assessing feasibility of nucleation for specific compounds.
