Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...

Co-design of a Jupyter Notebook for wood stove emissions analysis

Creator:: Schofield, Ryan
Abstract:: Designs for improved cookstoves aim to decrease the detrimental environmental and health impacts that are associated with traditional biomass cooking practiced by nearly 40% of the global population. Programs to provide improved cookstoves are found worldwide, and regional testing centers support development of these through emissions testing services. Aprovecho Research...

Realized regulatory complexity : unveiling the hidden effect of regulation structure on product architecture

Creator:: Robinson, David Myles
Abstract:: Government regulation is an established policy tool for inducing technological innovation in a market. For example, many environmental regulations prescribe performance requirements that industry complies with by innovating aspects of the product design. These design innovations might include updated components, new functionality, or a revised product architecture. However, the effect...

Development and validation of acoustic measurement techniques for void fraction in concentric annular geometries

Creator:: Tost, Brian C.
Abstract:: This work investigates the acoustic velocity of gas-liquid mixtures in vertical, co-current flow in a concentric annulus. Acoustic velocity shows promise as a detection parameter for the presence and amount of gas in a liquid flow because of its high sensitivity to gas void fraction in a gas-liquid mixture. However,...

Optical sensing and metrology for on-machine surface inspection in manufacturing processes

Creator:: Lee, Eddie T.
Abstract:: Optical sensing technologies are pivotal in the manufacturing process, specifically in defect detection, tool condition estimation, and monitoring. The research aims to enhance the accuracy, efficiency, and reliability of manufacturing metrology by employing optical sensing technologies, such as laser profilometers and image processing techniques. The dissertation proposes intelligent and flexible...

The Mira 2 Rocket Engine: Applying Lessons Learned for an Improved Iteration

Creator:: Dimas-Harms, Colton R.
Abstract:: In this paper, I present the design of Mira 2, a small-scale, liquid bipropellant rocket engine, with a specific focus on its oxidizer-centered pintle injector. Building upon the valuable lessons and insights gained from the empirical testing of its predecessor, Mira 1, the Mira 2 engine incorporates several improvements and...

Fluid dynamic analysis of fluid flow in a raceway tank for cultivation of macrophytic red algae, Gracilaria vermiculophylla

Creator:: Willis, Myles
Abstract:: As new cost-effective cultivation methods are needed for macrophytic red algae, this experiment expands upon a previously studied land-based approach. The experiment aimed to determine how the fluid dynamics of a previously researched land-based method affected the growth of the macrophytic red alga, Gracilaria Vermiculophylla. A clonal culture of G....

Design cycle models and knowledge management systems

Creator:: Popham, Kinsey
Abstract:: This thesis explores the relationship between design cycle models and knowledge management systems applied to various physical prototypes that the author developed from 2020 to 2023. The author walks through the process of prototyping a potty-training device in OSU’s Prototype Development Lab and an automated testing fixture for her Senior...

Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

Additive Manufacturing of FeCrCoCuNi High Entropy Alloy via Laser Powder Bed Fusion and Nickel Aluminum Bronze via Laser Directed Energy Deposition

Creator:: Doyle, Ryan P.
Abstract:: High Entropy Alloys (HEA) exhibit unusual properties and are gaining interest as new materials for challenging applications in the aerospace, hypersonic and medical fields. The application of HEAs have been limited by the development of powder production at scale. A recently developed process of plasma spheroidization by 6K, inc. has...
