Characterization of flow boiling in a fractal–like branching microchannel network

Creator:: Edward, Lee M.
Abstract:: Based on experimental investigations the present study evaluates flow instability and void fraction in a fractal-like branching microchannel network with rectangular cross-section. The hydraulic diameter of the channels ranged from 308μm at the inlet to 143μm at the outlet. The flow network used is characterized by set branching ratios for...

Discovery, Processing and Characterization of New Copper and Hafnium-based Metallic Glass Alloys

Creator:: Saini, Jaskaran S.
Abstract:: Metallic glasses (MGs), also called amorphous metals, are metals or metallic alloys trapped in a disordered glassy state. Their amorphous nature and absence of features such as crystal lattices and defects (dislocations, grain boundaries etc.) endows them with a host of properties that far surpass those of common crystalline materials....

Selective laser melting of 304L stainless steel: Role of volumetric energy density on the microstructure, texture and mechanical properties

Creator:: Ghayoor, Milad, Lee, Kijoon, He, Yujuan, Chang, Chih-hung, Paul, Brian K., and Pasebani, Somayeh
Abstract:: The role of volumetric energy density on the microstructural evolution, texture and mechanical properties of 304L stainless steel parts additively manufactured via selective laser melting process is investigated. 304L is chosen because it is a potential candidate to be used as a matrix in a metal matrix composite with nanoparticles...

Modeling in-situ vapor extraction during flow boiling in microscale channel

Creator:: Salakij, Saran
Abstract:: In-situ vapor extraction is performed by applying a pressure differential across a hydrophobic porous membrane that forms a wall of the channel as a means of reducing the local quality of flow boiling within the channel. As the local quality is reduced, the heat transfer capability can be improve while...

Characterization of expert solutions to inform instruction and assessment in an industrially situated process development task

Creator:: Sherrett, Ben U.
Abstract:: What constitutes a quality solution to an authentic task from industry? This study seeks to address this question through the examination of two expert solutions to an authentic engineering task used in the Chemical, Biological and Environmental Engineering curriculum at Oregon State University. The two solutions were generated by two...

Methodologies to improve reliability engineering in early design

Creator:: O'Halloran, Bryan M.
Abstract:: This thesis is the summation of two publications with the motivation to move reliability analysis earlier in the design process. Current analyses aim to improve reliability after components have been selected. Moving specific analyses earlier in the design process reduces the cost to the designer. These early design analyses provide...

Mechanical Design for Robot Locomotion

Creator:: Abate, Andrew M.
Abstract:: Robotic limbs have been shown to enable mobility in unstructured, real-world terrain; they allow robots to step around cluttered environments, scramble up hills, carry heavy loads, and even perform acrobatics. However, mechanical limbs cannot operate as a means for such dynamic locomotion if they are simply treated as general articulated...

Performance enhancement of a thermally activated cooling system using microchannel heat exchangers

Creator:: Wang, Hailei and Peterson, Richard B.
Abstract:: In the current study a thermally activated cooling system that combines an ORC system with a vapor compression cooling cycle was developed and tested under laboratory conditions. This combined system can utilize waste heat or other thermal sources such as solar and geothermal to generate power and cooling. Hot oil...

Advancing forced draft biomass cookstove technology with computational fluid dynamics modeling

Creator:: Cassidy, Liam J
Abstract:: Today, billions of people are limited to using biomass-fueled traditional fires as a primary energy source for cooking and purification of drinking water. Reliance on open burning of biomass leads to exposure to high levels of household air pollution which has been estimated to claim over 1.5 million lives annually,...

Care Team Burnout: Predictors and Potential Intervention

Creator:: Alshaiji, Rawan A M A J
Abstract:: Burnout is a state of physical or emotional exhaustion and disconnectedness induced by continuous stress that affects various aspects of an individual’s life. Physicians experience burnout at a higher rate than other professions due to the highly stressful nature of their work. Consequently, physicians are at a higher risk of...
