Stephen Monroe just completed his first year as an M.S. student in Mechanical Engineering at Clarkson University. He received his B.S. from Clarkson University in 2022. In his senior year, Monroe began learning CFD algorithms and HPC in the research group of Professor Chunlei Liang. During the first year of graduate study, Monroe conducted URANS studies of an ONR waterjet propulsion unit on parallel computers. He also is performing large eddy simulations of the same propulsion system to examine finer flow structures. Monroe is determined to become a skillful computational fluid dynamicist in large eddy simulations using an open-source code before completing his M.S. program. While uncertain about his future in academia, Monroe intends on using the skills he has developed to become a proficient propulsion system designer.“Coming into the Graduate School, I only intended on achieving an M.S. degree. Having been recognized for my hard work by the Abe Zarem award, not only has my passion for research been rejuvenated, but my consideration of furthering my education has as well,” said Monroe.
Monroe’s faculty advisor, Chunlei Liang, is Professor of Mechanical and Aerospace Engineering at Clarkson University. He received his Ph.D. from the University of London in 2005. Liang is an ASME Fellow and an AIAA Associate Fellow.
Quentin Roberts is an M.S. student at the University of Washington studying aeronautics and astronautics with a concentration in fluids. His research is on injector mixing in rotating detonation rocket engines (RDREs). Roberts will start work in fall 2023 as a propulsion analyst at Blue Origin. “Receiving this award will allow me to greatly expand my horizons in the world of astronautics by not only providing an opportunity to learn about what research the international community is working on, but also an opportunity to present my own research to an international audience,” said Roberts.
Roberts’ faculty advisor, Carl Knowlen, received his bachelor’s and master’s degrees in Aeronautical and Astronautical Engineering from the University of Washington in 1983 and 1985, respectively. He continued with his graduate research on ram accelerators at the UW and completed his Ph.D. program in 1991. Dr. Knowlen then accepted a Postdoctoral Research Associate position with the UW Department of Aeronautics and Astronautics and has been teaching AA Department courses on a regular basis since 2002.
