Computational Study of Smoldering Combustion in Cellulose and Hemicellulose Mixtures

Creator:: Mulky, Tejas Chandrashekhar
Abstract:: Due to global warming wildland fires are increasing in frequency and severity. In the case of wildland fires, the major modes of combustion occur include smoldering combustion and flaming combustion. Smoldering combustion occurs most commonly in porous fuels like peat, forest duff, and woody fuels, which are available in abundance...

Computational Modeling of Smoldering Combustion in Wildland Fuels

Creator:: Jayasuriya, Waduge Jayani A.
Abstract:: Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...

Solar-driven Dry Reforming Reaction in a Milli-scale Reactor

Creator:: Wang, Yige
Abstract:: Dry reforming of methane to syngas using CO2 was performed in a solar-driven milli-scale reactor, which converts solar energy to chemical energy. The process aims to upgrade the energy content of the feed stream using sustainable energy. The effect of mean residence time, temperature and CO2:CH4 ratio on conversion and...

Design And Testing Of A Flow Electrolyzer For Selective Seawater Electrolysis

Creator:: Chou, Kuan-Hsun
Abstract:: Hydrogen is of great interest as a fuel, as its oxidation produces benign water (without CO₂ emissions), its gaseous form can be transported in existing pipe infrastructure, and it can be obtained via renewable electricity from water. However, current hydrogen production is mainly produced from fossil fuels (e.g. methane), exacerbating...

Experimental investigation of supercritical heat transfer of carbon dioxide in parallel square microchannels with a single-wall constant heat flux boundary condition

Creator:: Zada, Kyle R.
Abstract:: In the vicinity of the pseudocritical point, supercritical carbon dioxide (sCO₂) undergoes a steep change in properties from “liquid-like” to “gas-like” as it is heated at a constant pressure. At the same time, there is a large spike in specific heat which can yield high heat transfer coefficients and heat...

Network Abnormalities in Routerless Networks on Chip

Creator:: Gambord, Ryan T.
Abstract:: Routerless networks on chip (NoCs) were recently introduced as an alternative to traditional mesh-based scalable networks, promising improved performance and scalability with a large decrease in power and area usage by the elimination of routing on in-flight packets. Without mitigation, most network designs, including routerless, are susceptible to loss of...

Predicting Properties of Bio-jet Fuels using Machine Learning and ATR-FTIR Spectroscopy

Creator:: Mayer, Morgan A.
Abstract:: High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

Investigation of Seasonal Performance of a Membrane Heat Pump System in Different Climate Regions

Creator:: Bukshaisha, Ahmad A.
Abstract:: Membrane based heat pumps systems have attracted the attention of many research groups as a potentially more environmentally friendly alternative to vapor compression systems that are being used for space cooling in 90\% of the buildings in the United States. Several prototypes systems have been developed, with reported claims of...

Numbering-up of parallel microchannel arrays to megawatt scale supercritical CO₂ solar thermal receivers

Creator:: Hyder, Matthew B.
Abstract:: Concentrated solar power (CSP) plants have the potential to reduce the reliance on nonrenewable energies such as coal and natural gas and provide 24 hour, renewable electricity. A CSP system consists of a large field of heliostats that concentrate the sunlight on a centralized receiver, in this receiver a working...
