|Project Code name||MADWEC (MECC 2)|
|Project Title||Design and Testing for MADWEC|
|Abstract||The maximal asymmetric drag wave energy converter (MADWEC) is focused on converting wave energy into electrical energy. The MADWEC system is a point absorber type wave energy converter. This year’s MECC Team will be a continuation of the Capstone team from a year ago.
Their device (patent pending by UMass Dartmouth) provides an efficient and lightweight way to stabilize a wave energy power take off (PTO) unit. The system provides translational motion between the spar of the system and the buoy, allowing for energy capture. The PTO will be housed between the tethered ballast and the buoy and consist of shafts, gearboxes, generators, and batteries. It will effectively translate the oscillating linear motion into a smooth rotational motion to the generators to create electrical energy. This energy will be stored in the batteries to provide a constant supply of power available at any moment. The primary market for this device will be related to using the stored power to recharge ocean surveillance vehicles such as Autonomous underwater Vehicles (AUV) and Unmanned Underwater Vehicles (UUV).
We have capitalized on their conceptual design in order to bring their ideas to fruition. Parts have been ordered, and the MADWEC system has been constructed. Our team is actively working on performing tests on this prototype, in order to ensure that the system functions as designed. After performing these tests, our team will compare our data to last years’ team, ensuring it’s as they intended. Taking another step further, our team will evaluate this data and come up with ways to improve the original design, so next years’ team can alter it and perform wet tests. The testing method that the MADWEC system will undergo is a Horizontal Dry Lab test. This will incorporate a table, which the system will be constrained to a variable speed winch, various pulleys, load cell, and tachometer. All of this will allow for data logging, relative to the amount of electricity that the system could produce. This is in regards to wave heights, ranging from 1-2 meters.

|Project Code name||Baja SAE|
|Project Title||ASME Baja SAE Powertrain Design|
|Abstract||During the past academic year, the UMass Dartmouth American Society of Engineers (ASME) Club sponsored a senior capstone project in which senior engineering students design, test and manufacture a complete powertrain for a Baja vehicle. The goal of this challenge is to apply technical engineering skills to a hands-on project by designing and building a four-wheel drive, off-road, racing vehicle. We were provided a budget of $3000 dollars to ensure proper design and manufacturing. In future years, the ASME club will continue work on other vehicle systems, eventually taking it to competition.
Baja SAE is not just a club activity. It is an intercollegiate design competition run by the Society of Automotive Engineers (SAE). Teams of students from universities all over the world design and build small off-road vehicles. With the same engines, success is not dependent on engine size or tuning, but rather overall design.
There are multiple dynamic events including a hill climb, maneuverability test, and suspension test as well as a single four-hour endurance race that pushes the vehicle. Teams are also assessed in static events such as ergonomics, functionality, cost, and manufacturability of their designs in a business and marketing presentation.
Students involved with the project will have the opportunity to apply their knowledge to real world, hands-on design. Projects like these enable senior students to learn the necessary skills that will help them become successful engineers in their future careers.

|Project Code name||Team EOM Offshore|
|Project Title||In-line tension measurement for stretch hose|
|Abstract||UMass Dartmouth’s Team EOM Offshore was tasked with designing a method to measure forces acting along EOM Offshore’s Stretch EM Cable. Their patented advanced mooring solution can stretch 2.5x its original length while still providing continuous data flow from the sea floor to the buoy above. The underlying problem is that conventional strain gauges are an unsuitable method of measuring the high strain values associated with the Stretch EM Cable. Over the course of our senior year, our team applied engineering knowledge acquired at UMass Dartmouth to design an out of the box solution to measure the strain by other means on the cable.|

|Project Code name||Free-Falling Spheres|
|Project Title||Free-falling super-hydrophobic ball in water|
|Abstract||Tasked by UMass Dartmouth’s own Dr. Hangjing Ling, the team designed, built, and tested the use of superhydrophobic coatings on different sphere materials. Beginning with thorough research to understand the topic, the team began developing the test in collaboration with Dr. Ling. This technology has drag reduction capabilities for use in the maritime industry to help improve efficiency and reduce their environmental impact.
Using COMSOL and SolidWorks, models and simulations were made to start the process of building and designing the test. The team collaborated to fabricate a reliable testing system for a drop test comprised of two parts: a tank and dropping mechanism. Once completed, the team was able to record preliminary results and compare the falling time difference between a superhydrophobic-coated and non-coated sphere of the same size and material. Using a variety of methods, the results were tabulated and prepared for our sponsor’s research on the topic.

|Project Title||Design, Development and Test of an Offshore vertical axis wind turbine|
|Abstract||Every year, the U.S Department of Energy (DOE) hosts a competition for university students across the nation to team up to offer an original solution to the flourishing marine energy industry that can play a major role in powering the blue economy. Our team is participating in this competition, with our project idea being provided to us by our sponsor and advisor, Dr. Banafsheh Seyed-Aghazadeh. Our project is split up into two portions: designing and manufacturing a small-scale wind tunnel, as well as developing and testing an offshore 3-bladed vertical axis wind turbine (VAWT) prototype. The wind tunnel would be utilized to test two phase flow, a method of mimicking various ocean and wind conditions that our offshore VAWT would experience in real-life conditions. Through multiple weekly meetings throughout the semesters, the team was able to design and manufacture the components for the wind tunnel. The completed components include the inlet, inlet reduction, outlet expansion, square to circle adapter, fan housing, straight test section, as well as the necessary electrical components needed, such as the motor, microcontroller, and other vital items. The potential seen in the offshore wind energy as a supply of clean energy resource has motivated an increased attention in the scientific community towards feasibility studies involving the fluid-structure interactions problem that could be experienced between the complex floating structure of the floating platform the surrounding fluid environment, i.e., wind, current, waves. The focus of this project is on the experimental study of stability and dynamic response of a scaled semi-submersible platform prototype, similar to those used in floating offshore wind turbines located further offshore in deeper seas, that are in interaction with its surrounding environment (wind, current and wave). The experiments were conducted in a recirculating water tunnel at the Fluid-Structure Interaction Laboratory at University of Massachusetts – Dartmouth. The scaled semi-submersible platform prototype was flexibly mounted and placed in the test-section of the water tunnel, using a one-degree-of-freedom air bearing set up that enabled the motion of the platform in the direction perpendicular to the flow. Then the scaled turbine and mooring lines were attached to the platform to be tested in the water-wind tunnel configuration. Flow-Induced Motion response of the system was studied over a wide range of flow velocities and platform’s angles of attack with respect to the incoming flow. The flow-induced motion amplitudes and frequencies were collected using laser displacement sensor at each flow velocity. Flow visualization was conducted at different angles of attack of the platform to study the vortex shedding patterns in the wake of the platform.|

|Project Code name||Fabreeka|
|Project Title||Fabreeka Pad Slitter|
|Abstract|| Fabreeka international is a company focused on the development and manufacturing of vibrations and shock isolation technologies. One of their core products is a thick composite rubber pad. The machinery currently used to cut these pads is becoming old and lacks desired design features, leading Fabreeka towards the development of a new machine.
Our team has been brought on to design and manufacture a new machine which will take in Fabreeka’s rubber pads and cut them down into strips. The machine will accomplish this task by driving the rubber pads by a series of rollers through a fixed blade. These rollers and blades will be adjustable to accommodate different thicknesses of materials, and different sizes of cuts, respectively. Along with the manufacturing of the machine, our team developed a comprehensive user repair and operations manual. This manual outlines the proper use of the device, as well as the needed information for any repairs or replacements.

|Project Code name||Water Treatment Plant|
|Project Title||Modular Ground Water Treatment Plant|
|Abstract||In the twenty first century, technology and possibility have evolved to great lengths for fast evolving world countries, redirecting from survival to expansion of knowledge. However, there are some developing countries focusing on day-to-day struggles such as the lack of proper water sanitation. Water quality is particular to the soil impurities varying largely by environment and location. XSyn Corporation, a United States based company, seeks to provide engineering-related services to better the water quality in Ethiopia. Seeking out the help of graduating University of Massachusetts Dartmouth Mechanical Engineering students, an attempt is made to design a unique and functional Mobile Water Treatment Plant design to tackle water quality issues wherever needed in Ethiopia. The purpose is to create an affordable, mobile, solar-powered water treatment plant in a freight container that removes the highest level of contaminants from local river or surface water. As a project based on intensive research, contaminants in river water found in the regions of Ethiopia were determined. A full water treatment operation will be designed with mobility in mind for the flexibility of transportation through dry seasons to be used in as many regions as possible. The water treatment plant will consist of two stages of three prefilters, granular activated carbon system as the main filtration, three bone char absorption filters, and Uv light sterilizer as the final stage. Overall, the final design has been made to process and clean water that comes from a nearby river for use in agriculture and for drinking.
