■ Award Summary
●Title: Jet Coronation
●Description:
When an impact is applied to a container filled with liquid, a thin liquid jet is generated.
This simple technique enables the ejection of highly viscous liquids and has potential applications in the injection and coating of materials such as paints and adhesives.
In this study, the researchers reported on the beautiful jet phenomena that occur under strong impact conditions.
Understanding these phenomena under various conditions is important for future engineering applications.
