Creator:: Pattee, Heidi Ann
Abstract:: When trace quantities of an alkali element are added to a flame, its optical and electrical properties change significantly. Addition of alkali seed to both premixed and diffusion flames has been used in the development of two new techniques, one for flame temperature measurement and the other for enhanced mixing....

Creator:: Cullion, Rebecca
Abstract:: Two-phase flow in a fractal-like branching microchannel heat sink may have enhanced heat transfer capabilities over single phase flow in the same branching channel network. In order to exploit this potential, a complete understanding of flow boiling in this geometry is required. The fractal-like geometry is similar to that of...

Creator:: Shen, Jian
Abstract:: This study investigates the hydrodynamic characteristics of droplet impinging on heated surfaces using High Speed High Resolution (HSHR) imaging and evaluates the effect of surface temperature and using water and a nanofluid on a polished and a nano-structured surface. Three types of surfaces are used in the study: polished silicon,...

Creator:: Daniels, Brian J.
Abstract:: A one-dimensional numerical model has been developed to study diabatic and adiabatic flow boiling in microchannels. This model accounts for developing flow effects and variable property effects. The model uses correlations for void fraction and two-phase multipliers found in the literature. The model has been used to study the performance...

Creator:: Yang, Guozhong
Abstract:: For piezoelectric stack (PZT) driven droplet generator, the driving waveform and driving frequency effect on liquid filament shape and droplet characteristics have been experimentally studied. The experimental study was based on a PZT driven droplet generator with known geometric design parameters and working fluid properties. A lumped-element-model (LEM) constructed to...
