The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded the University of Alabama in Huntsville $245,969 on February 15, 2026, under the Engineering program (CFDA 47.041) to investigate non-continuum hydrodynamic interactions in the growth of water droplets within warm cumulus clouds. The project develops an integrated large-eddy simulation and theoretical cloud model to capture droplet-scale physics across continuum and non-continuum regimes, addressing the 15–40 micrometer "size-gap" range where current cloud models fail to predict droplet growth rates and size distributions. The work combines state-of-the-art computational fluid dynamics with precise theoretical models for hydrodynamic, van der Waals, and electrostatic forces to bridge large-scale turbulent fluctuations in cloud thermodynamic properties and small-scale droplet interactions. The project trains undergraduate and graduate students in interdisciplinary research and conducts outreach to high school and undergraduate populations. Performance occurs in Huntsville, Alabama, with a period of performance through January 31, 2029. The award is structured as a project grant.
