Development and Trial of a Usability Testing Protocol for Biomass Cookstoves : An Interdisciplinary Approach

Creator:: Moses, Nicholas D.
Abstract:: Improved cookstoves have been designed and disseminated for several decades in an effort to address the human health and environmental issues caused by the inefficient, traditional biomass cooking and heating methods used by 40% of the world’s people. Engineers and designers working on these improved stoves have tended to focus...

The experimental characterization of membrane behavior in two-phase gas extraction

Creator:: Cappello, Nicholas C.
Abstract:: Understanding the behavior of hydrophobic membranes is important for applications where separating a gas from a liquid-gas mixture is beneficial. For example, in-situ vapor extraction can be used in microscale heat sinks to improve heat transfer and flow stability. In this study, gas is experimentally evaluated flowing through flexible polytetrafluoroethylene...

Robotic Actuation and Control with Programmable, Field-Activated Material Systems

Creator:: Bira, Nicholas P.
Abstract:: This dissertation presents novel, field-activated smart material systems for the actuation and control of autonomous robots. Smart materials, a type of material whose properties can be changed with an external stimuli, represent a promising direction to expand upon existing robotic control and actuation methods, particularly in the sub-fields of soft...

Event detection for avian and bat wildlife on wind turbine blades

Creator:: Drachnik, Nicholas
Abstract:: Countries have begun to adopt green energy initiatives requiring high percentages of power generation to come from clean energy sources. Both onshore and offshore wind energy generates reliable clean energy. Due to this, wind energy has had an exponential growth in global adoption. While wind energy is increasingly adopted by...

Adhesive Properties Subject to Variation in Temperature, Thickness, and Working Time

Creator:: Aerne, Nicholas, S. J.
Abstract:: Adhesive use is becoming increasingly common in manufacturing processes. The advantage of adhesives are light weight components, non-destructive fastening techniques and distribution of loads over the applied bond region. Modeling the behavior of adhesive bond lines in fastening joints can help in the design process to make an optimized joint,...

The Effect of Isothermal Aging on the Development of Long-Range Order in Ni-based Alloys

Creator:: Aerne, Nicholas S. J.
Abstract:: Nickel (Ni)-based alloys with a high chromium (Cr) content are frequently employed in applications where elevated temperatures and/or corrosive environments are present due to their excellent corrosion resistance and mechanical properties. However, a gap exists around the formation, and kinetics of long-range order (LRO) Ni2Cr phase in both model binary...

Turbulent Heat Transfer of Supercritical Carbon Dioxide in the Proximity of the Pseudo-Critical Point with Non-Uniform Heat Flux Boundary Conditions

Creator:: Jajja, Saad A.
Abstract:: Seven decades of supercritical heat transfer research have not seen an attempt to characterize turbulent thermal transport in internal flows subject to asymmetric heating. Existing heat transfer models therefore do not account for phenomena that dictates thermal transport, in the proximity of the pseudo-critical point, for non-uniform heating. Additionally, past...

Evaluation of system-level performance of closed thermochemical energy storage systems for space heating

Creator:: Rivera, Kate E.
Abstract:: This study evaluates the system efficiency and energy-offsetting capabilities of a closed-cycle thermochemical energy storage (TCES) system. Current TCES research primarily focuses on material selection and reactor design but overlooks the practical limitations faced on a system level. Thus, this study investigates various TCES integration methods for providing building space...

Accelerating Power-to-Gas Energy Storage Through PEM Electrolyzer Development and Technoeconomic Forecasting

Creator:: Taie, Zachary
Abstract:: There is strong interest in the energy community to develop technologies that can diffuse low-cost, renewably generated electricity into difficult and slow to decarbonize sectors. One of the emerging areas of interest is renewable natural gas (RNG). RNG has low or no associated net greenhouse gas emissions and can be...

Fourier-Transform Infrared Absorption Spectroscopy in Binary Hydrocarbon-Alcohol Single Droplet Evaporation

Creator:: Daly, Shane R., Olson, Nicholas, and Hagen, Christopher L.
Abstract:: Broadband absorption spectroscopy, by way of FTIR, was used to investigate the vapor cloud of a single millimeter sized liquid droplet suspended by a syringe as it evaporates at standard conditions. Single beam data were collected every 8 seconds resulting in a time-resolved record. Species concentrations were tracked using their...
