文摘
- •
Jet impingement with phase change on multi-scale porous surfaces is investigated.
- •
Porous coated flat, pin-fin, open tunnel, and closed tunnel structures are studied.
- •
Boiling curve, heat transfer coefficient, and pressure drop metrics are reported.
- •
Flow visualization shows vapor removal from the surface is a key aspect of design.
- •
The porous coated pin-fin surface exhibits superior two-phase cooling performance.
