Evaporation-induced non-wetting droplets on superhydrophilic surfaces
A droplet deposited on a rough, lyophilic surface satisfying the imbibition condition, results in spontaneous spreading and hence complete wetting. However, in this thesis, we demonstrate that this wetting behavior can be altered by superheating the substrate such that droplets can reside in a …

Analysis and feasibility of an evaporative cooling system with sessile droplet evaporation to provide cooling for microprocessors
… using diffusion based evaporation of sessile droplets. An analytical model is developed to determine the capacity of a single layer of droplets to provide sufficient cooling. It is found that a single layer can provide sufficient cooling for the processors with tiny droplets. A numerical model …

The impact of Arctic cloud water and ice on cloud radiative forcing during the Arctic Summer Cloud-Ocean Study in August 2008
… used together to constrain estimates of liquid droplet radius; constraining these radii shows the sensitivity of shortwave cloud radiative forcing and the insensitivity of long wave cloud forcing to changes in drop size.

A Numerical Simulation Optimizing Droplet Motion Driven by Electrowetting
… contact angle at the advancing triple point, and droplet overlap onto neighboring actuated electrodes. These parameters were investigated with respect to their effect on droplet locomotion performance. This performance was quantified by the droplets velocity and the dielectrophortic (DEP) force’s …

Modeling and measurement of sodium chloride and ammonium sulfate droplet growth in laminar flow
Cloud droplet growth is governed by a balance between vapor diffusion, Kelvin effect, and Raoult’s law, as expressed in K¨ohler theory. In this study, a thermodynamic droplet growth framework initially developed by Brewster and Li (2021) for radiation-induced cooling of pure water droplets is …

Assessing impact of the sulfate aerosol first indirect effect on tropical cyclone activity
… reflectivity) through parameterization of cloud droplet number, radius, and optical depth. Cloud droplet number is parameterized using an empirical scheme, while the radius is determined from cloud liquid water content and number concentration moments, and the optical depth scheme is embedded in …

Development of nanogels from nanoemulsions and investigation of their rheology and stability
Nanoemulsions with extremely small droplet sizes (<100 nm) have shown several advantages over conventional emulsions. However, almost all nanoemulsions in usage are liquids that restrict their use in many soft materials. The aim of this thesis is to understand the formation and long-term stability …

Droplets in an Electric Field: Surface Rheology, Coalescence and Rebound
… is the process in which pairs of conducting droplets suspended in a continuous dielectric (nonconducting) liquid phase are drawn together and merge upon the application of an electric field. The electric field polarizes each of the droplets in the field direction. The polarization causes the …

High order numerical methods applied to the analysis of transport phenomena in combustion
… vaporization and subsequent combustion of fuel droplets immersed in slowly convective flows. For small values of the Peclet number Pe, the convection associated with the velocity of the oxidizer stream is in first approximation negligible at distances to the droplet of the order of the droplet …
