Plasmon resonance measurements in pool boiling, condensation and evaporation experiments on a nanostructured surface

Surface plasmon resonance (SPR) is used in a wide range of applications, including biology, physics and materials science, because its ability to obtain sub-wavelength measurements from simple white light source, real time non-invasively. Surprisingly, this technique just beginning be the field phase change heat transfer, whereas fundamental phenomena occurring near interfaces, such as ice, liquid or vapour nucleation, require development innovative techniques capable reaching little-explored scale. In paper, grating-coupled SPR method implemented on aluminium samples which different liquid-vapour take place. The first goal work was study influence surface topography boiling phenomenon, particular presence geometrical patterns micrometric sub-micrometric scales, typical those necessary for implementation method. results show that mirror-polished surfaces covered with periodically structured grooves have best thermal characteristics amongst tested, similar small number holes evenly distributed over surface. Sub-micrometre scale corrugated being also ideally suited SPR, they were second part paper evaluate potential boiling, condensation evaporation. Although our optical test bench, limited by acquisition frequency, not able detect very fast birth nuclei at nucleate yet interest non-intrusive measure temperature vicinity wall, an essential measurement. addition, evaporation experiments provides useful means monitor formation nanoscale film acetone time. This exploratory opens perspectives understand small-scale occur during changes thus help develop functional promote delay their occurrence.
