Super-resolution reconstruction of turbulent flows with machine learning
Kai Fukami, Koji Fukagata, Kunihiko Taira
We use machine learning to perform super-resolution analysis of grossly under-resolved turbulent flow field data to reconstruct the high-resolution flow field. Two machine-learning…
Cluster-based feedback control of turbulent post-stall separated flows
Aditya G. Nair, Chi-An Yeh, Eurika Kaiser +3
We propose a novel model-free self-learning cluster-based control strategy for general nonlinear feedback flow control technique, benchmarked for high-fidelity simulations of post-…
Core-pressure alleviation for a wall-normal vortex by active flow control
Qiong Liu, Byungjin An, Motohiko Nohmi +2
We consider the application of active flow control to modify the radial pressure distribution of a single-phase wall-normal vortex. The present flow is based on the Burgers vortex…
Active attenuation of a trailing vortex inspired by a parabolized stability analysis
Adam M. Edstrand, Yiyang Sun, Peter J. Schmid +2
Designing effective control for complex three-dimensional flow fields proves to be non-trivial. Oftentimes, intuitive control strategies lead to suboptimal control. To navigate the…
Resolvent-analysis-based design of airfoil separation control
Chi-An Yeh, Kunihiko Taira
We combine three-dimensional (3D) large-eddy simulations (LES) and resolvent analysis to design active separation control techniques on a NACA 0012 airfoil. Spanwise-periodic flows…
Spanwise effects on instabilities of compressible flow over a long rectangular cavity
Yiyang Sun, Kunihiko Taira, Louis N. Cattafesta +1
The stability properties of two- (2D) and three-dimensional (3D) compressible flows over a rectangular cavity with length-to-depth ratio of is analyzed at a free stream Mac…
