Gold Surfaces for Dropwise Condensation
Gold surfaces were investigated as promoters of dropwise condensation of steam at atmospheric pressure. Seven gold electroplating baths, one electroless immersion gold plating bath, and vacuum gold vapor deposition were used as deposition techniques. Five different surface preparation techniques of …

Dropwise condensation on hydrophilic surfaces
Droplet nucleation and condensation are ubiquitous phenomena in nature and industry. Over the past century, research has shown dropwise condensation heat transfer on non-wetting surfaces to be an order of magnitude higher than filmwise condensation heat transfer on wetting substrates. However, the …

Silver Surfaces for Dropwise Condensation of Steam
The condensation of atmospheric pressure steam on copper coated with electroplated and vapor deposited silver was studied. It was found that, with a thick enough coating, silver will promote dropwise condensation without the intentional introduction of an additional promotor. For electroplating, …
