Research Overview
Prof. Troian's current research focuses on controlling the flow of liquid, heat or light in micro/nanoscale systems by spatiotemporal modulation of surface forces involving Maxwell, capillary, thermocapillary, Marangoni or van der Waals fields. Studies rely on mathematical modeling and numerical simulation of high-order nonlinear PDEs with and without noise; particle based modeling and non-equilibrium molecular dynamics simulation; and laboratory experimentation based on various microscopy and image processing techniques. Applications include
- 3D sculpting of micro-optical arrays for spatial or temporal beam shaping
- Electrohydrodynamic micropropulsion systems for space precision pointing
- Liquid cooling strategies for minimizing thermal boundary resistance in power dense CPUs
- Thermal rectification in small scale systems
- Self-propulsion mechanisms in active matter like Interfacial swimmers.
Research Summary: Transport phenomena in micro/nanoscale systems mediated by surface forces; Analysis and stability of micro/nanofluidic systems governed by high-order nonlinear PDEs; Electrohydrodynamic modeling for space micropropulsion systems; Noise and stochastic resonance; Mode filtering in micro-optical arrays; Thermal boundary resistance, thermal rectification and the Kapitza effect.
