Abstract: Flow is a fundamental engineering challenge affecting high-speed vehicles and jet engines performance. While the governing equations of flow help us understand various transport systems, capturing the complexities of turbulence and transitions remains difficult. Our research aims to refine this understanding by elucidating the such transition mechanisms of flow that impact performance. We explore the role of vortices near fluid machinery surfaces and are trying to control it in a practical way. Generally we employ turbulence models in aircraft development. By integrating statistical and theoretical models through data assimilation, we enhance flow predictions and reduce computational costs, making it beneficial for real-world applications. Additionally, we utilize magnetic suspension balance systems for accurate aerodynamic drag measurements without mechanical interference, and we are developing systems for high-speed flight and drag reduction device validation.

Bio: Prof. Aiko Yakeno is an Associate Professor at the Institute of Fluid Science, Tohoku University. After graduating from Osaka University, she entered the Graduate School of the University of Tokyo, and later studied at Imperial College London in the UK before obtaining her Ph.D. in Engineering from the University of Tokyo. Having served as a researcher at the Japan Aerospace Exploration Agency (JAXA) and the Japan Agency for Marine-Earth Science and Technology (JAMSTEC), she has been conducting research related to aerospace fluid dynamics at Tohoku University since 2017. A rising star in her field, Prof. Yakeno has received several prestigious awards, including the Ryumon Prize from the Japan Society of Fluid Mechanics, the Frontier Award from the Japan Society of Mechanical Engineers, and the Young Scientist Award from the Minister of Education, Culture, Sports, Science and Technology. Starting in 2024, she leads a large-scale research project aiming to bridge mathematics and engineering. Prof. Yakeno offers fresh perspectives on the role and challenges of fluid research in aerospace industry and is deeply interested in practical applications, not only through the conventional theory but also through more practical approaches.
