Mechanical Engineering MS Thesis Defense by Mr. Anthony Encarnacion DATE: May 14, 2024 TIME: 10:00 a.m. - 12:00 p.m. LOCATION: Science & Engineering (SENG), Room 110 Zoom link: https://us05web.zoom.us/j/88265834821?pwd=PTi4awzgy5dIWiXFI179B9jUP0ype5.1 (contact scunha@umassd.edu or aencarnacion for Meeting ID# and PassCode) TOPIC: The Development and Implementation of a MATLAB Based Model Representing the Power-Take Off Unit of a Wave Energy Converter ABSTRACT: This thesis presents the development and implementation of a MATLAB-based model designed to represent the Power-Take Off (PTO) unit of the Maximal Asymmetric Wave Energy Converter (MADWEC) device. The objective was to create a model based on empirical data and mechanical principles to accurately represent a table-top prototype of the MADWEC PTO. This model will serve as a predictive tool, analyzing the performance of the PTO unit under various wave conditions and enabling the selection of optimal configurations based on the deployment location or power requirements. The computational model incorporates the PTOs components, including a dual-dispensing reel, counterweight rewind mechanism, slip clutch, one-way clutch, gearbox, and generator. Leveraging the computational resources of MATLAB and its Simulink environment, the model was developed with an overall error of 1.36% compared to empirical data. This research details the development process of the model, including empirical data acquisition, analysis, and model optimization techniques. A performance estimation for the Nantucket Sound area indicated the potential power generation capabilities of the device, estimated at approximately 0.19 kilowatts an hour or 1.664 megawatts annually for that location. The study showcases a robust approach to predicting the efficiency and power output of MADWEC's PTO unit, providing a valuable tool for researchers and engineers in the field of renewable energy. It contributes to the understanding of WEC operations and supports the advancement of marine renewable energy systems by aiding in the design and optimization of WEC prototypes.

UMass Dartmouth has selected Qualtrics as our Internet survey tool. All Faculty and Staff have access to create and publish their own surveys. Students may also use Qualtrics under the direction of a Faculty or Staff member. This workshop covers the authoring and administration of surveys, as well as data collection. Question types are covered in detail. No previous survey experience is necessary. Note that access to Qualtrics is managed by the Office of Institutional Research and Assessment. Please contact Jonathan Bonilla at JBonilla1@umassd.edu at least three business days prior to this workshop to request access. Students must have a Faculty or Staff advisor request access on their behalf. This workshop will take place via Zoom teleconference. The Zoom meeting link will be sent to registered participants via email the morning of the workshop. For more information about Zoom, visit http://instructionaldev.umassd.edu/zoom . For more information about this workshop, contact Rich Legault at 508-999-8799 or email rlegault@umassd.edu.
