Art and science are two fields that appear to be worlds apart at first glance, but according to George Matheou, assistant professor of mechanical engineering, the intersection between the two are actually extremely important. This notion became the inspiration behind his art exhibit called Fluid Dynamics in Art and Nature at the William Benton Museum of Art.
During the 45th Annual Design Automation Conference, held by the American Society of Mechanical Engineers (ASME) this past summer, Mechanical Engineering Professor Julián Norato has been awarded the prestigious Design Automation Young Investigator Award.
Prof. Norato receiving the award from Prof. Chris Mattson on behalf of the Design Automation Committee
This award is given once each year “to recognize an outstanding young investigator who is making noteworthy contributions in the area of design automation, including research in design representation, design optimization, design evaluation, and/or design integration.” The award was presented at the ASME’s Design Automation Conference, which was held on August 18-21, 2019 in Anaheim, California. This conference brings together every year international experts in the field of design automation.
Norato was given this award based on the work and research he has done in topology optimization. Topology optimization is a computational methodology to automatically design parts to maximize structural strength with minimal amounts of material in the most efficient and effective way. A major focus of Norato’s research group is to do the topology optimization employing exclusively certain shapes, like bars or plates, that make manufacturing with conventional processes easier.
An example of the work Norato does with topology optimization
Prof. Christopher Mattson presented the award to Prof. Norato “in recognition of his expertise in topology optimization, specifically his advances in stress-based topology optimization and development of the geometry projection method” and to “recognize his continuous and dedicated service to the Design Automation Conference and his outreach to the community.”

The power you feel underneath you when you’re on a plane as it takes off is tremendous. The physics that enable the remarkable feat of lifting a 175,000-pound midsize commercial aircraft into the sky and keeping it there are just as incredible – and complicated.
There are four components to a commercial aircraft gas turbine engine: the fan that produces most of the thrust, the compressor, which compresses the incoming air, the combustor which burns the fuel to create high-energy gas, and the turbine that produces work from that gas to power the fan and exhaust to produce additional thrust.
The challenge in this system is keeping the flame in the combustor burning. Flame blowoff can occur when the air flow speed is very high, or the fuel-air mixture is weak so that the flame cannot be stabilized, so it moves downstream and eventually extinguishes itself.
University of Connecticut professor of mechanical engineering, Baki Cetegen has received $320,000 from the National Science Foundation to study this problem by investigating how different fuels and high levels of flow turbulence affect the occurrence of flame blowoff.

The UConn School of Engineering is proud to announce that Mechanical Engineering Professor Chih-Jen Sung has been recognized as one of the 2019 Class of Fellows for The Combustion Institute.
Sung joins a class of 38 accomplished international scholars from industry, academia, and the public sector, and was recognized for “novel contributions to flame dynamics and structure, and development of rapid compression machines to enhance understanding of low-temperature chemistry.”
After a four-year vacation, the Historic Keney Clock is telling time again thanks to senior design project completed by Mechanical Engineering students seniors Henry Courchaine ’19, Garrett Murphy ’19, and Spencer Padget ’19 advised by Thomas Mealy. The project was a collaboration between UConn, the City of Hartford and Friends of Keney Park.
Through our Senior Design Program, directed by Prof. Vito Moreno, industrial sponsors put the bright UConn ME undergraduate students to work on a real-world problem that they are interested in researching, while reaping the benefits of our faculty’s experience and expertise. The renovation of the Historic Keney Clock Tower is one of the more than 65 senior design projects that Mechanical Engineering students worked on during the 2018-2019 academic year.

Through our Senior Design Program, industrial sponsors put the bright UConn ME undergraduate students to work on a real-world problem that they are interested in researching, while reaping the benefits of our faculty’s experience and expertise. For students, this program is an opportunity to synthesize and apply the classroom engineering knowledge they have acquired. They delve further into various aspects of product development process, and are experiencing first hand how ethics affect engineering decisions, how professionals communicate ideas and the day-to-day implications of design decisions and of intellectual property.
Here is a podcast, part of Simsbury Bank’s “Manufacturing Matters” initiative, in which CEO Martin Geitz discusses a UConn Engineering Senior Design partnership with EDAC Technologies that has provided a mechanism to hire some of our talented engineering graduates while providing solutions to one of the company’s major challenges.
