The Influence of Gas Extraction on Bubble Dynamics

Creator:: Juarez, Corey D.
Abstract:: A new thermal management method for hotspots on microprocessors is under development that employs confined pool boiling with vapor extraction at pre-determined nucleation sites. Extraction is accomplished by locating a vacuum chamber constructed out of a glass tube and a hydrophobic membrane directly above a nucleation site. In order to...

A study of solidification dynamics with liquid mass influx

Creator:: Thirunavukarasu, Balamurugesh
Abstract:: A computational model is developed to study the effects of alumina layer formation on an ablative surface when exposed to high temperature particle laden gas flow. The solidification dynamics i.e., the solid and liquid alumina layer growth rate, and the heat transferred to the ablative surface are investigated. A one-dimensional...

Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

Creator:: Strahl, Jordan D.
Abstract:: The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....

Passive pumping in pool and open channel configurations via meso-scale asymmetric surface patterning

Creator:: Strid, Logan
Abstract:: The research presented in this thesis is a continuation of collaboration between Oregon State University and Auburn University studying the feasibility of passively pumping liquid during boiling in a preferential direction using meso-scaled asymmetric surface patterns. Such a passive phase-change mechanism has great potential for thermal management in spacecraft and...

Simulation of drag reduction due to multi-aligned spheres

Creator:: Lindqvist, Varna
Abstract:: A method was sought to predict the flight paths and collisions for closely spaced ink droplets of various sizes as a design aid for ink-jet printing development. Computational fluid dynamics models of two rigid aligned spheres, as a proxy for ink droplets, were initiated in atmospheric pressure air at constant...

Mechanically Enhanced and Optically Compatible Hydrogels for Particle Image Velocimetry in Porous Flow

Creator:: Cornwell-Arquitt, Luke
Abstract:: Hydrogels have been attractive for use as a medium in porous flow studies, but have always been limited in this role because of their poor mechanical properties. This project analyzes and tests two recently developed hydrogels, poly(methacrylamide-co-methacrylic acid) (PMM), and a heat-treated long chain PVA hydrogel. Particle image velocimetry (PIV)...

Combustion Characteristics of a Jet Fuel and its Surrogate in MILD Conditions

Creator:: Weide, Parker D.
Abstract:: This research seeks to identify how changes in temperature and oxygen concentration in the reaction zone affects liftoff heights for moderate or intense low-oxygen dilution (MILD) combustion of a jet fuel and a surrogate fuel. MILD combustion offers a method of burning fuels with reduced CO and NOx production by...

Analysis of spillway hydrodynamics for total dissolved gas prediction downstream of hydropower projects with free, plunging spillway jets

Creator:: Germann, Nathan A.
Abstract:: During spring and early summer hydropower projects are often forced to spill water through their spillways due to increased river flows of the runoff season. Flows which are directed through spillways--instead of through turbines--contain a substantial amount of energy. Stemming from the high energy content, spillway flows entrain air at...

Experimental study of two-phase gas-liquid flow in a microscale fractal-like branching flow network

Creator:: Kwak, Younghoon
Abstract:: Two-phase gas-liquid flows in microscale fractal-like branching channel flow networks were experimentally studied to assess the validity of existing void fraction correlations and flow regimes based on superficial gas and liquid velocities. Void fractions were assessed using two different methods. First, void fraction data were acquired using a High-Speed-High-Resolution (HSHR)...
