A cyclic perspective on transient gust encounters through the lens of persistent homology
Luke Smith, Kai Fukami, Girguis Sedky +2
Large amplitude gust encounters exhibit a range of separated flow phenomena, making them difficult to characterize using the traditional tools of aerodynamics. In this work, we pro…
Optimal waveform for fast synchronization of airfoil wakes
Vedasri Godavarthi, Yoji Kawamura, Kunihiko Taira
We obtain an optimal actuation waveform for fast synchronization of periodic airfoil wakes through the phase reduction approach. Using the phase reduction approach for periodic wak…
Sparse sensor reconstruction of vortex-impinged airfoil wake with machine learning
Yonghong Zhong, Kai Fukami, Byungjin An +1
Reconstruction of unsteady vortical flow fields from limited sensor measurements is challenging. We develop machine learning methods to reconstruct flow features from sparse sensor…
Grasping Extreme Aerodynamics on a Low-Dimensional Manifold
Kai Fukami, Kunihiko Taira
Modern air vehicles perform a wide range of operations, including transportation, defense, surveillance, and rescue. These aircraft can fly in calm conditions but avoid operations…
Laminar post-stall wakes of tapered swept wings
Jean Hélder Marques Ribeiro, Jacob Neal, Anton Burtsev +3
While tapered swept wings are widely used, the influence of taper on their post-stall wake characteristics remains largely unexplored. To address this issue, we conduct an extensiv…
Image and video compression of fluid flow data
Vishal Anatharaman, Jason Feldkamp, Kai Fukami +1
We study the compression of spatial and temporal features in fluid flow data using multimedia compression techniques. The efficacy of spatial compression techniques, including JPEG…
