CONFIRMED: MNE MS Project Presentation by Mr. Adam Fiore
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. ADVISOR: Dr. Sankha Bhowmick, Professor/Chairperson, Department of Mechanical Engineering, UMass Dartmouth COMMITTEE MEMBERS: Dr. Hangjian Ling, Assistant Professor, Department of Mechanical Engineering, UMass Dartmouth Mr. James LaCroix, HII Corporate Director, Huntington Ingalls Industries (HII) Open to the public.
