Rational Fuel Design for Low Temperature Internal Combustion Engines

Creator:: Daly, Shane R.
Abstract:: This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...

Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...

Wave Energy From Idea, to Concept, to Converter: Structuring Methods for Design and Evaluation of Wave Energy Devices

Creator:: Trueworthy, Ali May
Abstract:: The amount of energy we use and the ways that we get that energy sit on the edge of dramatic change as the carbon budget which can keep the planet under 1.5C of global average temperature increase gets smaller (Allen, 2018). In response, we continue to research and develop renewable...

Multi-Scale Study of Ember Production and Transport under Multiple Environmental and Fuel Conditions

Creator:: Hudson, Tyler R.
Abstract:: Spot fires caused by lofted embers (i.e., firebrands) can be a significant factor in the spread of wildland fires. Embers can be especially dangerous near the wildland-urban interface (WUI) because of the potential for the fire to be spread near or on structures. Many studies have investigated the transport of...

Effects of Residual CO2 and N2 on Detonation Velocity and Detonation Limits

Creator:: Glad, Harley R.
Abstract:: Detonation combustion has gained interest throughout the years because of its potential to increase thermodynamic cycle efficiency when compared to deflagration based cycles. The expected benefits result from a pressure gain during the combustion process instead of a pressure drop, as observed for deflagrations. The implementation of detonations can be...

Radiation Emissions from Turbulent Premixed Jet-A/Air Flames Diluted with Combustion Products

Creator:: Hoter, Zohar R.
Abstract:: Heat flux measurements of radiation emissions from turbulent premixed flames diluted with N 2 and CO 2 were taken to identify sensitivities of radiation heat loss to diluent fraction and species. This work is motivated by the desire to better characterise radiant heat transfer in the presence of combustion products,...

Ignition of Fuel Beds by Firebrands

Creator:: Bean, Derek R.
Abstract:: The severity of wildfires around the globe is increasing. At the same time, urban development is expanding outward into areas where severe fires occur. There is an increased risk of home loss to fires in areas where severe fires and urban expansion meet. Ignition of homes or nearby fuel is...

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...

Design, Fabrication, and Evaluation of a Novel High-Performance Resistance Heater Rod for Nuclear Thermal Hydraulic Experimentation

Creator:: Sharaf, Salem A.
Abstract:: The Accident Tolerant Fuels campaign demonstrated a need for nuclear fuel pin simulators to further research fuel and cladding combinations that can withstand off normal conditions in light water reactors. The use of a heater rod as a fuel pin simulator greatly reduces the risk involved during testing as no...
