Boiling heat transfer is a common and efficient heat transfer method, it occurs in both reactor cores and steam generators. Boiling heat transfer is affected by many factors, among which the surface characteristics have a significant effect on boiling heat transfer. The boiling heat transfer ability can be improved by regulating the surface characteristics. This paper focuses on the effects of surface characteristics such as surface roughness, wettability and microstructures on boiling heat transfer, which involves in relevant experimental research methods and main conclusions. This paper also combs the research route on the influence of surface characteristics on boiling heat transfer, and further points out that the future development direction is the fine research on the influence of coupled macroscopic and microscopic scale surface characteristics parameters.
