Abstract: In this inaugural lecture, I will present some past and ongoing research topics on linear and nonlinear fluid modeling. I have focused on better understanding complex fluid phenomena using reduced-order modeling and linearized fluid dynamics. These approaches are useful for predicting the onset of fluctuations and extracting the dominant physics of the flow system. However, by their definitions, these models are limited when it comes to nonlinear dynamics. This limitation can be addressed by using quasi/semi-linear models, which remain simpler than the full nonlinear modeling. I will showcase some examples of these modeling techniques. Then conclude the lecture with future research topics on applying these modeling techniques to fluid phenomena in hydropower.
Biography: Eunok received her B.Sc. and M.Sc. degrees in Mechanical Engineering from KAIST, Korea, in 2010 and 2012, respectively. She pursued her Ph.D. studies in vortex stability analysis at LadHyX, École Polytechnique, Palaiseau, France, and received her degree in 2015. In 2016, she worked as a postdoctoral researcher at M2P2, Aix-Marseille University, on transitions to turbulence in rotating flows. From 2017 to 2020, she continued her postdoctoral research at LFMI, EPFL, on various types of stability analysis and reduced-order models. She then broadened her expertise in industry by working at GE Renewable Energy, Hydropower, from 2020 to 2024. Since June 2024, she has been appointed as a Tenure Track Assistant Professor in the Mechanical Engineering department at EPFL. Her research interests encompass fluid stability, numerical modeling, and applied fluid dynamics for hydropower research.
