Infrared Imaging of Water Condensation on Hydrophobic, Hydrophilic, Superhydrophobic, and Lubricant-Infused Surfaces.
This project studied condensation on a lubricant-infused surface, a hydrophobic surface, a hydrophilic surface, and a superhydrophobic surface, during which the temperature gradient and movements of droplets were recorded. Dropwise condensation behaves differently across samples with different types of coating. On a hydrophilic surface, droplets have a tendency to coalesce and wet the surface. A water film will form as condensation equilibrates. Hydrophobic and superhydrophobic surfaces tend not to be wetted by droplets, which stay distinct during condensation. On lubricant-infused surfaces, the high droplet mobility on the lubricant helps the droplets to retain their circular shape and promote long-term stable dropwise condensation. With the mobility and temperature distribution across condensation captured by the infrared (IR) camera, the heat rate across these types of surfaces can be estimated.
