TIME CHANGE Mechanical Engineering MS Project Presentation by Mr. Adam Fiore DATE: December 6, 2024 TIME: 9:30am-11pm LOCATION: Science & Engineering (SENG), Room 110 (Materials Science Lab) TOPIC: Engine Bay Thermal Analysis of a Medium Class Unmanned Surface Vessel ABSTRACT: An unmanned surface vessel has the capability of operating remotely, semi-remotely, or fully autonomously (conducting missions without human intervention), while being equipped with advanced sensors and payloads for intelligence, surveillance and reconnaissance (ISR). Operating without personnel onboard demands the need to identify the possibility of system component failures that may occur due to out-of-operating range temperatures. In this project, a thermal finite element analysis (FEA) and computational fluid dynamics (CFD) shall be conducted on a medium class unmanned surface vessel, provided by the project's sponsors Huntington Ingalls Industries Uncrewed Systems Division (UxS). These studies consider both the vessel traversing the ocean at a maximum speed of 40 knots for a time duration of 10 and 4 hours and the vessel stationary at a pier during two extreme environmental conditions. These extreme environments include ambient temperatures of 115F and -20F and seawater conditions of 95F and 31F. With the vessel's internal engine bay and components being the largest source of generated heat, this shall be the interest of this project. The analysis in SOLIDWORKS models the temperature and heat transfer between components and flags minimum and maximum temperature conditions and locations. All while simulating variable environmental and system boundary conditions. A final report summarizing the results within the engine bay was provided to the project's sponsors, UxS, and included in this project. A standard operating procedure (SOP) of thermal FEA/CFD practices in SOLIDWORKS was provided to the company to apply the same methods on all system components of the MUSV. Areas of future design improvements of the MUSV are discussed briefly, Finally, future studies to better understand the effects of system components on the MUSV that contribute to high temperature changes within the engine bay are discussed.

Title: "First Principles Study of Metal Hexacyanometallates as Potential Booster Material for Redox Targeting Flow Batteries" - by Kayode O. Ojo Abstract: With the growing demand for high-efficiency, large-scale energy storage, redox flow batteries (RFBs) have become an important option in renewable energy systems. However, improving the performance and efficiency of RFBs remains challenging. This study explores the use of metal hexacyanometallates as solid boosters in redox-targeting flow batteries (RTFBs), which will act as a solid storage material participating in multiple redox reactions to enhance performance. Metal hexacyanoferrates are known for their tunable redox properties, mixed-valence states, and structural stability, making them strong candidates for application in RTFBs. Using first-principles density functional theory calculations with the Perdew-Burke-Ernzerhof generalized gradient approximation, we assessed the reduction potentials of various metal (Cu, Co, Fe, and Mn) hexacyanoferrates. Our calculations showed that iron and cobalt hexacyanoferrates exhibited the highest reduction potential among the tested materials, indicating their strong potential as effective boosters. Simulated IR spectra further identified key vibrational modes critical to understanding redox mechanisms, with potassium ion intercalation revealing additional vibrational modes. Post-intercalation, a redshift and increased intensity in CN stretching modes were observed, consistent with experimental data and validating the computational approach. Future research will focus on the effects of potassium, sodium, and lithium-ion intercalation on enhancing the reduction potential, as preliminary results suggest that ion intercalation could significantly boost redox activity. This work advances the understanding of how metal hexacyanometallates can enhance the energy storage capacity and efficiency of RTFBs, offering new avenues for optimizing battery technologies.
