This thesis compares the implementation of additive manufactured suspension uprights against subtractive manufactured suspension uprights from concept generation, design, and validation through simulation. Additive manufactured suspension uprights were designed for Global Formula Racing’s 2023 electric vehicle. Utilizing Siemens NX, Nastran, Fusion 360, and Ansys Workbench both subtractive and additive manufactured...
Combustion emissions produced from burning real transportation fuels have many environmental impacts. However, detailed chemistry across multiple phases, time scales, and thermodynamic conditions make predicting combustion emissions challenging. Detailed modeling of the gas phase alone is prohibitively expensive, due to the large size and stiffness of the kinetic models. The...
Food waste (FW), brewery waste (BW), and fats, oils, and greases (FOG), are prevalent waste streams in municipalities across the country, particularly in the Pacific Northwest (PNW). Anaerobic digestion (AD), the microbial-mediated transformation of organic waste into methane-rich biogas, offers a sustainable, energy-generating, waste management solution for these wastes. Anaerobic...
In recent years, non-renewable and non-biodegradable plastic packaging forms the majority of landfilled waste. These products, mainly made from Polyethylene Tetraphlatate (PET) and other polyolefins, have excellent durability and barrier properties, but take hundreds of years to degrade.
Much focus has been put on developing environmentally friendly alternatives to polyolefins...
Modular construction is increasingly seen as an efficient construction method in terms of time, cost, and energy. The full realization of these advantages partly relies on the efficiency of the production process inside the modular factories, which currently rely on tedious manual monitoring methods or expensive automated techniques. As a...
Tsunami inundation of coastal communities can impose a wide array of forces on the
built environment. Forces generated by tsunami-driven debris damming have the potential to
cause failure of coastal structures and further accumulate flow-entrained debris. Since tsunami-resilient design standards were adopted by ASCE in 2016, debris damming considerations have...
As the development, processing, and manufacturing of plastic has improved over the years, so has our amount of plastic waste. Currently, only approximately 9% of post-consumer plastics get recycled. The other 91% is buried in landfills, burned, ends up in the ocean, or is accumulating in communities without access to...
Wind energy is one of the fastest growing renewable forms of energy in the United States and the world. However, interactions between wind turbines and wildlife have the possibility to injure animals such as birds and bats. Strategies to assess and minimize wind turbine interactions with wildlife are critical for...
The electrical conductivity data of ceramic material at high temperatures can be useful in the application of modeling, solid oxide fuel cell (SOFC), and magnetohydrodynamic (MHD). The existing data is considerably lacking at extreme temperatures. Our research focuses on bridging this gap by reporting the electrical conductivity measurements of sets...
The rapid accumulation of plastic waste in landfill, waterways and oceans is becoming a critical problem, one that current recycling technologies are not capable of solving. Recent proposed approaches in the depolymerization of waste plastics employ an Olefin-Intermediate Process (OIP), where feedstocks like polyolefin plastics are ‘activated,’ producing an olefin...
