Abstract:Objective: Phase-change heat transfer enhancement is of critical importance
to meet high cooling demands.
Method: Recently, surface engineering (surface structuring) has emerged as a promising
heat transfer enhancement method, especially with the development of nanotechnology.
Surface parameters such as wettability, surface roughness and porosity are modified by
surface engineering.
Aims: This work aims to discuss the parametric effects of wettability, surface roughness
and porosity on pool boiling heat transfer performance by selecting several promising
micro/nanoscale enhancement techniques as examples.
Conclusion: More efforts are needed as phase-change phenomena on micro/
nanostructures are complicated due to the multiscales of the engineered micro/
nanostructures and the length-scales of the bubble dynamics.
