The seminar series aims to provide a platform for research interaction and expose UDC faculty and students to a broad perspective on cutting-edge research and practice in engineering and applied science fields. CAM-STAR provides the researchers with an opportunity to develop their interpersonal skills, extend their network of research activities, share their latest research achievements, and set the stage for future research collaborations with distinguished CAM-STAR faculty and promising researchers.

Our areas of interest for the guest seminar series lie in, but are not limited to: Additive Manufacturing, Nanofabrication, Thermal Management Systems, Sustainable and Renewable Energy Systems, Energy Harvesting and Storage, Robotics, and Artificial Intelligence.

Due to the COVID-19 situation, the guest lecture series are currently held virtually/online. However, under normal circumstances, in-person guest lectures will be resumed with covering the entire travel expenditures for the guest lecturer.

If you are an active researcher, either independent or affiliated, in one or more of the research areas addressed above, you are welcome to contact Dr. Mehdi Kabirnajafi to designate your lecture topic and schedule your lecture’s date and time through:

Upcoming Event

Development of a Porous Ejector Burner to attain combustion stability

Mohammad Azizi, Department of Mechanical Engineering, University of Isfahan, Iran

Tuesday, September 29, 2020
Virtual Seminar
11:00 to 11:45 am

ABSTRACT: Ejector burner is an ejector whose primary flow is a gaseous fuel to be expanded along a converging-diverging nozzle with no moving parts where the secondary flow, that is, air, is dragged by the primary flow to be mixed with. In spite of typical applications of ejectors mainly used for mixing and transferring fluids, an ejector burner is aimed to efficiently provide pre-mixed combustion conditions of fuel and air for the combustion chamber in a diffuser. Although ejector burners provide a gently homogeneous mixture of fuel and air, one challenge concerning the performance of ejector burners is an unstable combustion developed in the diffuser, leading to the fluctuating flame propagation. The solution proposed in this study to overcome the challenge is to take advantage of a porous medium at the inlet of diffuser to dampen the flame instability. As the implication of the proposed approach, the flame propagation is spontaneously managed to retain a completely stable combustion.

BIOGRAPHY: Mohammad Azizi is a Ph.D. Candidate of Mechanical Engineering at the University of Isfahan, Iran. He holds a Master’s degree in Mechanical Engineering from Tarbiat Modaress University – Tehran, and works as an R&D Engineer in Chaharmahal Sugar Company. His area of research interests lies primarily in Ejector Applications, Vacuum Systems, Combustion, Compressible Flow, Experimental and Statistical Studies.

UDC Firebird Rover Team for NASA Human Rover Challenge 2020

Each year, NASA organizes the NASA Human Exploration Rover Challenge that features an engineering design challenge to engage students worldwide in the next phase of human space exploration. The annual event is a more complex follow-up to the successful NASA’s Great Moonbuggy Race. The competition challenges high school and college students to create a vehicle designed to traverse the simulated surface of another world.

NASA’s Great Moonbuggy Race engaged more than 10,000 students and demonstrated that these budding scientists and engineers were capable of complex work. The NASA Human Exploration Rover Challenge continues that tradition by providing an authentic engineering experience. Student teams design, build and test technologies that enable rovers to perform in a variety of environments. The Rover Challenge inspires participants to become the engineers to design NASA’s next-generation space systems. This challenge brings the competitors from top U.S. institutions and teams from various continents.

UDC Firebird Rover team has participated in NASA Human Rover Challenge 2020 and was selected as one of the top teams for the Drivetrain Technology Challenge by NASA Human Rover Challenge 2020. Due to COVID-19, NASA Human Rover Challenge 2020 cancelled in-person competition and decided to move to virtual competition instead, and Drivetrain challenge is the main competition this year.

Our team leader this year: Giancarlo D’Orazio and Voss Harrigan gave a presentation to audience from NASA.

2020 NASA RASC-AL Competition

The NASA’s 2020 Revolutionary Aerospace Systems Concepts – Academic Linkage (RASC-AL) competition, is an annual university-level engineering design challenge that allows students to work on real challenges and provide innovative solutions that can be used to advance human exploration of space. Competition themes range from designing systems and architectures for exploring the Moon and Mars to envisioning how astronauts will best take advantage of existing and future assets as explorers venture far from our home planet.

For the 2020 RASC-AL competition, undergraduate and graduate teams developed new concepts that leveraged innovations for NASA’s Artemis program. NASA will send the first woman and next man to the Moon, enable sustainable lunar operations, and provide the foundation for humanity’s next giant leap, sending astronauts to Mars. This year’s competition moved beyond science and engineering to economics, with a theme dedicated to the analysis of future business opportunities that take advantage of space –extending to just beyond the Moon’s orbit–to improve the human condition.

The UDC Mechanical Engineering undergraduate student and CAM-STAR scholar Voss Harrigan and two under graduate students from School of Business and Management, Mayumi Fleming and Kyle Kelley, have successfully competed in 2020 NASA RASC-AL competition.
