Message from the Head

Rao Govindaraju

The 2021-22 school year saw a long-awaited return to normalcy. Events and celebrations that had been either made remote or outright cancelled the past couple of years have all began to return to campus. As if matching with the changing of the seasons, the vibrancy at Purdue University has only continued to grow since the beginning of the Spring Semester.

Capping off the school year was, of course, our commencement ceremony where we saw family and friends return in force to campus to celebrate our 150 students who earned their undergraduate and graduate degrees. The event, like the months leading up to the end of the school year, demonstrated the incredible dedication and efforts of our students, faculty, and staff over the years to ensure our campus remained open and safe, despite the pandemic.

Looking ahead now, I am left with a much more encouraging feeling of awaiting the next set of events to come, rather than primarily focusing on working to ensure we make it through safely. In this edition of eConnections, we share the many accomplishments of our alumni, students, faculty, and staff — as well as key research and partnerships that will potentially lead to a dramatic change in how both Purdue and the United States approach clean power and infrastructure advancements.

We are truly experiencing the spring and summer seasons here at Purdue and I cannot wait to see what spouts up and blooms next. And I hope to see many of your return to campus to celebrate with us this coming school year.

All the best,

Rao S. Govindaraju
Bowen Engineering Head of Civil Engineering
and Christopher B. and Susan S. Burke Professor of Civil Engineering

Purdue and Duke Energy to explore potential for clean, nuclear power source for campus

Purdue University and Duke Energy announced in April that they plan to jointly explore the feasibility of using advanced nuclear energy to meet the campus community’s long-term energy needs.

With interest rising worldwide in new technologies that are reliable and carbon-free, Purdue and Duke Energy intend to study power produced through Small Modular Reactors (SMRs), a move that may be unprecedented for a college campus and a potential fit for Purdue’s energy needs.

According to the International Atomic Energy Agency, SMRs are among the most promising emerging technologies in nuclear power. Significantly smaller than traditional nuclear power plants, an SMR could meet current and future needs for Purdue’s West Lafayette campus as well as provide excess power to the state’s electric grid. Home to one of the nation’s top nuclear engineering programs and a national leader in energy innovation that is scalable and sustainable, Purdue and its experts are uniquely qualified to evaluate this “giant leap” toward a carbon-free energy future.

“No other option holds as much potential to provide reliable, adequate electric power with zero carbon emissions,” said Purdue President Mitch Daniels. “Innovation and new ideas are at the core of what we do at Purdue, and that includes searching for ways to minimize the use of fossil fuels while still providing carbon-free, reliable, and affordable energy. We see enough promise in these new technologies to undertake an exploration of their practicality, and few places are better positioned to do it.”

Duke Energy Indiana President Stan Pinegar said, “Duke Energy is leading the industry’s biggest clean energy transformation nationwide, and exploring technologies such as this is important work to help get us there. Nuclear provides reliable energy and can complement other carbon-free energy sources, such as solar and wind. As the largest regulated nuclear plant operator in the nation, we have more than 50 years of experience with safe, reliable operations. We can share that experience with one of America’s premiere engineering schools to see what this technology could do for its campus as well as the state.”

Purdue is currently powered through the Wade Utility Plant, which is a combined heat and power system that uses steam to provide heat, electricity and chilled water that is used to cool facilities. A new Duke Energy plant on campus also provides thermal energy in the form of steam to Purdue, while also supplying Duke Energy’s Indiana customers with electricity. Approximately 50% of campus electricity is purchased from Duke Energy.

SMRs are revolutionary in part because of their modular nature. They can be prefabricated off site, thereby saving money and time in construction. And Purdue is at the forefront of this technology by pioneering, developing and verifying the steel-plate composite construction used in SMRs at the on-campus Bowen Laboratory through the Center for Structural Engineering and Nuclear Power Plants, which is led by Amit Varma, Purdue’s Karl H. Kettelhut professor of Civil Engineering and director of the Bowen Laboratory of Large-Scale CE Research.

“Steel-plate composite technology is fundamental to successfully deploying SMRs within budget and on schedule,” Varma said. “We have the world's pre-eminent team and facilities to conduct the testing, analysis, design, and construction demonstration to actualize the potential of this technology.

Invention addresses the problems of running a red light at traffic intersections

An invention from Purdue University and the Indiana Department of Transportation that uses wireless communication devices could save lives at high-speed traffic signals.

Principal research analyst Howell Li and transportation research engineer Jijo Mathew of the Joint Transportation Research Program in Purdue University's Lyles School of Civil Engineering have collaborated with Tom Platte at the Indiana Department of Transportation to create technology that improves safety as vehicles approach a signalized intersection.

According to the Federal Highway Administration, 2 million crashes occur annually at intersections with traffic signals, leading to hundreds of thousands of injuries and more than 3,000 fatalities.

Mathew said a driver's decision to stop at a traffic signal or continue through it is made at the onset of the traffic signal turning yellow. He said a section of roadway upstream of an intersection, known as the dilemma zone, is an area where a vehicle can neither stop safely nor clear an intersection at its present speed.

"To reduce crashes, the key idea is to provide dilemma-zone protection," Mathew said. "One would think yellow time can be extended; however, drivers tend to adapt to this, resulting in lower probabilities of stopping. The state-of-the-practice for actuated intersections – intersections where timing is influenced by sensors – is to use green extensions, where the green time is extended for a certain period when a vehicle is present. Although this reduces the exposure of vehicles to the onset of yellow, this can go only for so long."

The Purdue-INDOT technology extends green time or indicates yellow early as necessary to ensure safety and efficiency to the next intersection on a 0.1-second basis. The system would consider the trajectory of each vehicle relative to a predetermined time of when the green would end. If there is enough time to spare, the green is extended until the vehicle clears the intersection. However, when there are other vehicles competing for green time on other movements, the system would indicate yellow early before the vehicle enters the dilemma zone for a safe stop.

Li said the innovation improves upon traditional technology that extends green-light signals in several ways.

"Infrastructure sensors have a fixed range, are expensive, may require intrusive installation on existing infrastructure, and need routine maintenance to ensure proper operation," Li said. "And most sensors do not detect vehicles continuously one mile away to adjust timing changes, such as when the onset of yellow occurs."

A YouTube video featuring Li explaining how technology works is available.

The technology uses wireless communication devices placed at traffic signals and in vehicles, and specialized control logic at the signal controller to bring it all together. Li believes barriers for his technology can be overcome.
