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...
Powder Metallurgy Hot Isostatic Pressing (PM-HIP) is a widely recognized powder metallurgy manufacturing process to produce near-net-shape and net-shape components. During general PM-HIP processes the metal powders are filled within a capsule (die), heated and loaded with high pressure simultaneously, and solidified to form the final product. Due to the...
With the increased demand for high-quality products, reliable and robust process monitoring has become a key capability for modern manufacturing systems. Through sensors installed in the machinery, the real-time information was measured to assess the state of the processes. The measured data can be used to infer the mechanical, material,...
This work explores the mechanical properties of single-phase niobium alloy C103 from room temperature to 600°C for the purpose of expanding safe uses of the material into new applications. The study utilizes a symmetrically notched triaxial tensile specimens to manipulate the internal stress field in order to observe the changes...
The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...
Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...
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...
Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...
Designs for improved cookstoves aim to decrease the detrimental environmental and health impacts that are associated with traditional biomass cooking practiced by nearly 40% of the global population. Programs to provide improved cookstoves are found worldwide, and regional testing centers support development of these through emissions testing services. Aprovecho Research...
