FUNDAMENTAL STUDIES ON THE EFFECT OF ELECTRIC FIELD ON INTERFACE INSTABILITY, FILM BOILING, AND FILM CONDENSATION
… STUDIES ON THE EFFECT OF ELECTRIC FIELD ON INTERFACE INSTABILITY, FILM BOILING, AND FILM CONDENSATION MAJOR PROFESSOR: Dr. A. Esmaeeli This research focuses on investigation of uniform electric field on three inter-related interfacial phenomena including interface under electric field, film …

Numerical modeling of interface dynamics and transport phenomena in transport-limited electrolysis processes
… in materials and processes induce morphological instability on the cathode, which can lead to porous deposits or system failure. The growth of the protrusion is a complex phenomenon which involves chemical, electrical, and momentum driving forces in the system. Thus, it is important to understand …

Numerical simulation of dendritic growth of binary alloys
… a fixed mesh for the temperature and an adaptive interface-conforming mesh for the concentration. The temperature is solved on the whole domain while the concentration is solved only on the liquid region because diffusion in the solid is much smaller than that in the liquid and can be neglected. …

Carrier Transport and Electrical Conduction in Alloy-Mediated Graphene on Silicon
… conduction. Subsequently, we find that the interface instability is due to the diffusion of carbon into the silicon matrix during the 3C-SiC growth, creating electrically active interstitial carbon. We overcome these challenges using 3C-SiC on a highly-resistive silicon substrate. By …

Spreading behavior of molten metal microdroplets
… linear perturbation theory is developed for the interface instabilities of a radially-expanding, liquid sheet in cylindrical geometries. The theory is then applied to rapidly spreading droplets as the fundamental mechanism behind splashing. The effects of such factors as the transient profile of …

Stress Effects on Phase Morphological and Compositional Non-uniformity in Intercalation Compounds
… and solute-poor phases could cause the flat interface between them to become unstable and develop non-planar morphology during interface- and diffusion-limited intercalation processes, which is analogous to the well-known Asaro-Tiller-Grinfeld instability in epitaxial thin film growth. …

Vertical Transport of Sediment from Muddy Buoyant River Plumes in the Presence of Different Modes of Interfacial Instabilities
… that investigate two different modes of instability, one driven by sediment settling and one driven by fluid shear. The settling-driven and shear-driven instability sets of experiments were carried out in a stagnant stratification tank and a stratification flume respectively. In both …

Mixed-Phase Solidification of Thin Silicon Films on Silicon Dioxide
… subsequently proceeding primarily laterally at interface-location specific rates as determined by the local curvature and local temperature at a point in the solid/liquid interface. By analyzing the cross-sectional profile of solid/liquid interface, we correlate the local curvature of the …

Seeking Understanding of Acoustics and Spray Character in a Three-Stream Pulsating Transonic Airblast Injector
… energy is sourced in local shear layer instability development), however, a state-of-the-art hybrid model (newly implemented for this effort) appeared to be necessary to capture the resulting droplet scales. Lastly, droplet size and characteristic flow length scale predictions for two …
