Quantifying The Vulnerability Of Smooth Dogfish And Winter Skate To Electromagnetic Fields From Offshore Wind Transmission Cables In The Mid-Atlantic Shelf, Rachel A. Sechrist
Theses, Dissertations and Culminating Projects
The development of offshore wind structures in the northeastern U.S. will contribute to renewable energy goals, but will overlap with many marine species as well as economically important fisheries. High voltage transmission cables from offshore wind farms emit electromagnetic fields (EMFs) that elasmobranchs may detect using sensory organs known as ampullae of Lorenzini. However, sensitivity to EMFs varies by species due to differences in the number and arrangement of pores, the length of subdermal canals within the ampullae of Lorenzini sensory network, and the habitats they reside and regions they forage. For species who reside or forage in benthic regions, …

Renewable Energy Community (REC) is an emerging concept that empowers local customers to generate decentralized renewable energy. Integrating RECs into the building industry presents a promising opportunity to support the transition toward net-zero cities. However, the viability of RECs depends on regional regulatory frameworks, permitted governance structures, and very importantly, business models. Compared to pioneering European countries, Canada lacks the regulatory support needed to fully enable REC. This paper proposes and evaluates various business models for potential REC implementations under Canada's existing regulatory constraints. The analyzed models focus on "behind-the-meter" electricity distribution, a multi-stakeholder type of REC, where generation occurs …

Streamer Discharge Modeling For Plasma-Assisted Combustion, Stuart Reyes, Shirshak Kumar Dhali
Electrical & Computer Engineering Faculty Publications
Some of the popular and successful atmospheric pressure fuel/air plasma-assisted combustion methods use repetitive ns pulsed discharges and dielectric-barrier discharges. The transient phase in such discharges is dominated by transport under strong space charge from ionization fronts, which is best characterized by the streamer model. The role of the nonthermal plasma in such discharges is to produce radicals, which accelerates the chemical conversion reaction leading to temperature rise and ignition. Therefore, the characterization of the streamer and its energy partitioning is essential to develop a predictive model. We examine the important characteristics of streamers that influence combustion and develop some …
