Designing A Recycling Facility For Energy Materials, Bartholomew Kitko, Matthew Berger, Elias Chiti, Trayce Harris, Mark Kulesa
Williams Honors College, Honors Research Projects
The purpose of this design project is to create a recycling facility for energy materials. Different energy systems will be analyzed to determine the most economically appropriate energy material to recycle. A list of the energy systems to be analyzed includes catalyst converters, wind turbines, lithium ion batteries, photo-voltaic cells, and precious materials with high energy applications. This study involves two main parts: the research to determine the most appropriate energy material for recycling, while also choosing or creating recycling processes efficient enough to reduce the US’s reliance on foreign nations for obtaining their rare-earth materials. The second part is …

The wake flow in a wind turbine array boundary layer is described using the Koopman operator. Dynamics of the flow are decomposed into the linear and forcing terms, and the low-energy delay coordinates are revealed. The rare events show the non-Gaussian long tails that capture the switching and bursting phenomena. The near-wake region shows the incoherent phase space region, where the dynamics are strongly nonlinear. The far-wake region is marked with the small non-Gaussian forcing term, and the dynamics are largely governed by linear dynamics. The data-driven predictive model is built based on the Hankel-based dynamic mode decomposition and treats …
