The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded Worcester Polytechnic Institute $272,110 on August 15, 2026, for collaborative research on thermal transport and freezing mechanics of supercooled water droplets impacting superhydrophobic and ultrasonically vibrating surfaces, with application to aircraft and wind turbine de-icing under the Engineering program (CFDA 47.041). The research develops theory, methodology, and experimental techniques to understand nucleation and solidification of supercooled droplets—which remain liquid below 0°C down to approximately −40°C in laboratory conditions. The project employs ultra-fast X-ray and high-speed optical imaging to characterize the physics of freezing nucleation when supercooled droplets contact various solid surfaces, and investigates nucleation interactions with traveling ultrasonic structural waves. The work addresses gaps in prior research that concentrated primarily on post-impact solidification, assumed constant nucleation rates, or did not examine interactions among ultrasonic waves, superhydrophobic surfaces, and droplet impact dynamics. Ice accumulation on aircraft and wind turbines remains a significant operational and safety problem; this framework is designed to enable new approaches to ice prevention or delay. The project includes mentoring of high school and college students in applying analytical tools to engineering problems. Performance occurs in Worcester, Massachusetts, with period of performance through July 31, 2029. The funding is classified as a Project Grant, an assistance type providing support for research and educational activities.
