A Novel Coating Technique to Enhance Steam Condensation on Horizontal Tubes

ABSTRACT CTS-9624060 Paul J. Marto This proposal is to investigate enhanced film condensation on tubes. A combination of hydrophilic and hydrophobic coatings will be used to selectively control drainage from the tube. The tube surface will be coated with a very thin titanium layer, followed by a gold layer to which self-asqembled monolayers of organic molecules will chemisorb. Successful augmentation using this passive technique could have important implications for the power generation, refrigeration, and desalination industries.
