Through undergraduate research, two co-op students explored the VR technology (engine) and developed the framework for a learning module that will present fundamental notions in renewable energy sources, using scenarios based on physical experiments. We developed a virtual reality learning platform and the modeling of the VR framework and applied it to several experimental modules: wind turbine, solar cell (PV) module, a water decomposition and fuel cell module. Students explore concepts as parametric characterizations of the system as well as thermochemical characterization. The module is packed in an executable app, which is downloadable and usable in both VR STEAM immersive environments as well as in a desktop format. Future work will include beta-testing and preliminary assessment of the VR Renewable Lab, followed by its course implementation.","PeriodicalId":187039,"journal":{"name":"Volume 9: Engineering Education","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122802049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Rover Challenge participants are tasked with designing and fabricating a two-person human-powered rover capable of traversing a course designed by NASA to simulate various terrain. Based on the success over the years, a team was once again formed in 2020 to improve the previous design and develop students’ areas of proficiency in additive manufacturing and sensor integration. This was done by leveraging UDC’s new NASA-funded Center for Advanced Manufacturing in Space Technology & Applied Research (CAM-STAR) and its additive manufacturing facilities. In this paper, the authors will introduce the rover competition for 2020, new changes for the competition, and UDC team’s news design, AM produced parts for the rover, and lesson learned and plan forward. This paper will also discuss how a diverse population of students were engaged and their feedback on this experiential learning experience. Lastly, this paper will also discuss the impact of infusing cutting-edge technology (i.e., Additive Manufacturing) in STEM project and how it has helped attract students and increase their career readiness.","PeriodicalId":187039,"journal":{"name":"Volume 9: Engineering Education","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132681236","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Undergraduate Research Integration is a project for students which is about writing a proposal report and giving presentations. Each team writes a research proposal during the course of the semester that involves the use of biomass composites. The proposal is assigned in the third week of the semester and is due at the end of the semester. Student teams performed a preliminary study to create, test, and document a new environmentally friendly material that will be used in their dorm insulation. This project introduces sustainable engineering issues to students. Students also have to bring biomass material samples collected from nature as a project deliverable. Adaptability, communication, and management skills influences the way people interact and engage with colleagues. Placing students in groups and giving them tasks that they depend on each other is a great way to utilize the social needs of students. Overall, increased level of student enthusiasm was observed compared to previous years. Students were engaged in group meetings and often lead asking questions at the group presentations in class.

The thermal fluid sciences (TFS), including thermodynamics, fluid mechanics, and heat transfer, are infamously challenging core engineering subjects. TFS is traditionally taught through lectures, problem sets, and small projects starting in the second or third year of engineering curricula. However, pure PBL is often reserved for after students have completed the traditional courses. This case study follows a student who experienced a reversed pedagogy, wherein pure PBL instead of traditional lectures drove TFS education. In a summer invention program after the principal student’s first year, he invented a novel door fan that improved air circulation between adjacent rooms, even with the connecting door closed. He used computational fluid dynamics (CFD) to simulate his invention. He then enrolled in a formal CFD class in his second year without taking prerequisite TFS courses. Afterward, the student enhanced the CFD simulations of his invention and wrote a technical paper on his results. This case study analyzes the pros and cons of the reversed pedagogy and the early timing of pure PBL through the principal student’s experience.","PeriodicalId":187039,"journal":{"name":"Volume 9: Engineering Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131218563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The derivation of the equations of motion follows Hamilton’s principle and requires the calculation of virtual angular velocities and the corresponding virtual rotational displacements. The goal of this paper is to present a projection-based approach, which only requires knowledge of Euler’s first and second law, that results in the same equation of motion. The constraints need not satisfy d’Alembert’s principle and the projection is based on a generalization of Gauss’ principle of least constraint [14]. One advantage of the proposed method is that it avoids variational principles and therefore is more accessible to undergraduate students. In addition, the final form of the equation of motion is more easily understood. We motivate our approach using the example of the simple pendulum, derive the main result, and apply the methodology for derivation of the equations of motion for a modified Chaplygin sleigh and a rotary pendulum.","PeriodicalId":187039,"journal":{"name":"Volume 9: Engineering Education","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133144589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thorough analyses involve all three tools to inform design decisions or postmortem investigations. However, few undergraduate fluid mechanics lab experiences expose students to the simultaneous application of these tools to a common problem. In this paper, we discuss a set of exercises and lab activities spanning multiple weeks to study a cylinder in a crossflow, providing students with their first experience in the use and comparison of analytical, experimental, and numerical tools for studying a fluid flow.\u0000 The analytical approach involves the solution derived for potential (inviscid) flow around a cylinder. While no novel examples or analytical approaches are used to teach this portion of the experience, this idealized flow solution is used as a comparison for experimental and numerical lab activities.\u0000 The experimental approach was initially designed to leverage low-cost microcontrollers and MEMS-based pressure sensors while reinforcing mechatronics and related programming content used in previous courses. Over four years of use and iteration, it has evolved from instructors supplying only a C++ library for the pressure sensors, a wiring diagram, and a rough programming framework to a simplified MATLAB interface that abstracts away many of the low-level commands required to complete the lab exercise. This range of interfaces and experiences allows instructors flexibility in their own implementation and lab goals. The latest iteration includes the use of a hot-wire anemometer, which must be calibrated by students, and allows for data capture and analysis of the resulting vortex street formation and Strouhal number.\u0000 The numerical approach uses a transient 2D planar analysis for flow around a cylinder and leverages a commercial computational fluid dynamics software, Ansys, for which there are free student versions. Students are provided with an instructor-built flow domain and mesh capable of providing a mesh-independent solution. Students choose solvers, set boundary conditions, run simulations, and process resulting data to compare with analytical and experimental results. A transient analysis is used to capture the effects of vortex formation on the coefficient of lift and to calculate and compare the system’s Strouhal number with that found from the physical experiment.\u0000 Students are challenged throughout the experience, from completing classic problems such as the lift force on a Quonset hut, to automating sensor positioning and data collection, to simulating a transient fluid flow. A concerted analysis of this relatively simple geometry affords students the opportunity to use analytical, experimental, and numerical tools to compare drag forces, pressure distributions, and transient flow behaviors.","PeriodicalId":187039,"journal":{"name":"Volume 9: Engineering Education","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131022017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
