文摘
- •
Experimental results show large enhancement in nucleate boiling with increasing surface roughness.
- •
Recorded transient growth, departure diameter and detachment frequency of vapor bubbles on smooth and rough cu surfaces.
- •
Growth rate and departure bubble diameter on smooth Cu are higher than on rough surfaces.
- •
Estimated densities of active sites for bubble nucleation confirm the measured enhancements in nucleate boiling.
