Turbine Aerothermodynamics Laboratory researcher wins 2020 AIAA Best Paper Award
A researcher from the Turbine Aerothermodynamics Laboratory won the 2020 American Institute of Aeronautics and Astronautics (AIAA) Gas Turbine Engine Best Paper Award.
Mohammad Arif Hossain, a recent graduate research assistant at the Aerospace Research Center, presented his winning paper at the 2020 AIAA Aerospace Science Forum (AIAA SciTech 2020) in January 2020. Hossain was advised by Jeffery Bons.
The paper is about developing innovative cooling architectures for turbine engines. The objective of this research effort was to explore innovative cooling architectures enabled by additive manufacturing techniques for improved cooling performance and reduced coolant waste.
Hossain reached these objectives by developing a novel turbine Nozzle Guide Vane (NGV), design after an extensive and systematic research and development effort, he said.
“The final vane design consists of sweeping jet film cooling holes on the suction surface, sweeping jet impingement holes at the leading edge and double-wall partial length triangular pin-fins with impinging jets at the trailing edge,” he commented.
After all that time put in, Hossain was thankful that his work paid off.
“It always feels good to be recognized,” Hossain said. “AIAA is one of the biggest platforms for engineers and researchers in the aerospace industry and this recognition will allow us to highlight our research in front of a broader audience. This is also a testimony to the quality of the work that we do in our lab.”
Hossain shared his gratitude for his advisor, Professor Bons, for his constant support and guidance, and Professor James Gregory and Ali Ameri, PhD, for their expert opinion during the project. He also wanted to recognize the U.S. Department of Energy for financial support and the Ohio Supercomputer Center (OSC) for the computational resources.
Hossain graduated with a PhD in mechanical engineering from The Ohio State University in May 2020 and started a new role as a Senior Research Specialist at the Core R & D of the DOW Chemical Company. He will be working on developing innovative technologies for future additive manufacturing processes and related technical solutions using engineering analysis, computer simulation, and experimental studies.
