This project is a continuation of the project “Infrared Imaging of Water Condensation on Hydrophobic, Hydrophilic, Superhydrophobic, and Lubricant Infused Surfaces” . Condensation is a ubiquitous scenario in nature where a vapor cools down and loses energy, causing its molecules to form liquid droplets. For water condensation, such a phase change releases large amounts of heat. Depending on the medium on which condensation occurs, the rate of heat being transferred differs. Condensation that occurs on a hydrophilic surface is considered to transfer heat slower as compared to that occurring on a lubricant infused surface or a hydrophobic surface, because in the latter cases, droplets are more mobile and easily move across the surface. This project images condensation on a lubricant infused surface and a hydrophobic surface.
Parallel to conducting dropwise condensation experiments, the infrared (IR) camera was calibrated, because, through several experiments, it was found to output incorrect and nonuniform temperature profiles. Calibration for the IR camera is done by exposing the IR camera to a known temperature profile and associating its photon emissivity output to the known temperature.
