Effect of surface structure and coating on the heat transfer deflection behavior in the early stage of nucleate boiling

Under-liquid dual superlyophobic nanofibrous polymer membranes achieved by coating thin-film composites: a design principle

“…As is well-known that the wetting behaviors on the rough surface can be reflected by the apparent contact angles, which are determined by the surface geometries25,29,30 and the chemical compositions 28,31,32. For instance, in the Wenzel wetting model (the liquid fully permeates and wets the surface), the lyophilicity or lyophobicity of surfaces with intrinsic contact angle smaller or larger than 90° can be enhanced with the increase of the surface roughness 33–36.…”

Micro-Nano Scale Surface Coating for Nucleate Boiling Heat Transfer: A Critical Review

“…For nanofluids in NBHT, researchers also reported both enhancement and decline of CHF and HTC [95][96][97]. The settlement of nanoparticles increased the surface roughness [98] and wettability [99], and hence boiling performance but on the other hand suspended nanoparticles in nanofluid might have hindered the movement of the bubbles and caused a decrease in the overall heat transfer performance [100,101]. In all these and similar investigations, the results were always compared by changing the surface from clean to nanoparticle-deposited surface and keeping the nanofluid same.…”
