“…El-Genk and Ali [16] investigated saturation boiling of PF-5060 dielectric liquid on copper micro-porous surfaces with different thicknesses, and the nucleate boiling results showed better performance with dielectric liquids on micro-and macro-structured surfaces. Values of CHF are 40-70% higher and more than 17 times those reported on plane surfaces.…”

Evaporation of pure water out of Cu micro-porous dendrite surface layers is investigated. These layers are deposited on Cu substrates using twostage electrochemical process. The basic microstructure obtained in the first stage using current density of 40A/dm2 was further strengthened by continuing electrochemical deposition employing much lower current density of 2.5 A/dm2. Scanning Electron Microscopy (SEM) shows that the layers have porous dendrite structure. Samples were submitted to a water-thermal treatment to make them hydrophilic. Their evaporation capability was tested using a simple setup. Tests for determining of the liquid permeability and porosity are also carried out.

“…Until now, many kinds of microstructures have been observed, such as microstructured [8], diamond particle [9], micro-re-entrant cavities [10], porous surfaces [11], carbon nanotubes [12], nanowires arrays [13], octagonal micro-posts, or ZnO nanorods, or both [14], Cu micro-porous surface layers [15] micro-fin arrays covered with porous structure [16], microstructured surfaces with a wide range of well-defined surface roughness [17] and metallic foam surface with crossing and single-directional V-shaped groove [18]. These surfaces can actually enhance boiling heat transfer by increasing nucleate site number and effective boiling heat transfer surface area.…”
