This National Science Foundation (NSF) Engineering program (CFDA 47.041) Project Grant award, totaling $920,715, aims to elucidate the roles of gravity on the freezing dynamics of sessile drops in the presence of soluble and insoluble particles. The research will be conducted at the University of Illinois and involve several key tasks: fabricating samples and solutions for experiments on the International Space Station (ISS), coordinating with NASA to prepare the experimental rig, overseeing test runs and final experiments on the ISS, and performing thorough data analysis. Additional tasks include obtaining on-ground results with varied surface orientations and conducting phase-field simulations to understand freezing dynamics, shape evolution, solute segregation, and solutal Marangoni flows. The research outcomes are expected to inform the development of novel anti-icing coatings, advance manufacturing processes like freeze casting, and create new freezing desalination systems. The high-quality experimental data from the ISS will also help improve existing freezing models. This award aims to foster educational opportunities for undergraduate students, particularly those from underrepresented communities, by engaging them in hands-on experimental and computational work.
