Void fraction variations in a fractal-like branching channel network

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...

Hydrodynamics of droplet impingement on heated surfaces : effects of nanofluid and nano-structured surface

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,...

Effect of PZT driving waveform and frequency on meniscus shape and dropon-demand droplet formation parameters

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...
