UC Lab for Interfacial Dynamics (UCLID)
The University of Cincinnati Lab for Interfacial Dynamics (UCLID) is an interdisciplinary lab with experimental and computational capabilities for studying transport at curved liquid-vapor interfaces such as drops, bubbles, menisci, and thin films. We study liquid-vapor phase change at a fundamental level using theory, on-earth and in-space experiments, and multiscale modeling from molecular dynamics to CFD. We use what we learn to develop next-generation microscale phase change and thermal management devices, enable technologies for the hydrogen economy, solve thermal-fluid management problems in microgravity, address issues in the food-water-energy nexus, and improve advanced manufacturing processes.
What we bring:
- Multiscale, predictive modeling of evaporation, condensation, and wetting, with no tuning coefficients (research)
- Extreme-environment experiments: neutron imaging of cryogenic hydrogen and methane, and analysis of International Space Station data
- Interfacial diagnostics: interferometry, ellipsometry, high-speed imaging, and acoustic sensing
- Innovation in engineering education: CFD projects scoped to each student’s research and career goals (several have led to publications), a gamified Thermodynamics course, and classroom tools built in-house for live comprehension feedback and AI study assistance (teaching)
