May 2019: senior design presentation

Once again MTFL members presented their senior design projects as oral presentations as well as poster presentations at the College of Engineering Senior Design Expo event. This year, 3 projects were completed by MTFL members. In one project, William Yameen, Nathan Piascik, and Riccardo Clemente designed and assembled an experimental setup which allowed them to test heat transfer performance of air-water heat exchangers. They also designed three manifold-microchannel heat exchangers which were ultimately fabricated by additive manufacture (also known as 3D printing). The fabricated heat exchangers were from a stainless steel alloy and were tested at different air and water flow rates. The outcome of their senior design project was 2 conference papers which were presented at IEEE ITherm 2019 conference in Vegas, NV, and ASME Summer Heat Transfer conference in Seattle, WA. Click here to see their IEEE conference paper and here to see their ASME Summer Heat Transfer paper.
In another project, Cory Arden and Joseph Connors studied the effect of gas diffusion layer (GDL) compression on water percolation within the plane of the GDL. They applied different pressures on GDL samples and visualized water percolation with a CCD camera. In addition, they measured liquid water pressure during the injection to the surface of the GDL.
In the third project, Logan LaCroix designed and assembled a machine that can be used in the fin dropping process in baseboard factories. This project was sponsored by Mestek in Westfield, MA.
