Micro-patterned superhydrophobic/superhydrophilic surfaces for enhanced heat transfer during nucleate boiling [Elektronski vir]Zupančič, Matevž, 1990- ; Sedmak, Ivan, 1978- ; Golobič, IztokApplication of polydimethylsiloxane-silica based coating used for the development of micro-patterned biphilic surfaces for enhanced heat transfer is investigated using a high-speed video and a ... high-speed infrared (IR) thermography during saturated pool boiling experiments. Using developed florescence microspectroscopy system, the surface temperature fluctuations under the growing microbubble were measured with a spatial resolution of 370 nm. The highest CHF was achieved on uniform, superhydrophilic surface that was more than 350% of that on bare, stainless-steel surface. Increased wettability reduces the bubble contact diameter, allows a higher density of active nucleation sites, and delays the dry-out. The biphilic sample with the smallest hydrophobic spots of 250 x 250 [micro]m[sup]2 surrounded by the superhydrophilic network exhibited the highest measured heat transfer coefficient. Because of the high-dimensional dynamics, the nucleate boiling process must be considered in the spatio-temporal domain. The probability density of the wall temperature during saturated water pool boiling at different heat fluxes on the superhydrophilic, hydrophobic and biphilic surfaces are presented.Source: Boiling & condensation 2015 [Elektronski vir] (F.
