Resolvent analysis of compressible laminar and turbulent cavity flows
Yiyang Sun, Qiong Liu, Louis N. Cattafesta +2
The present work demonstrates the use of resolvent analysis to obtain physical insights for open-cavity flows. Resolvent analysis identifies the flow response to harmonic forcing,…
On the formation of three-dimensional flows over finite-aspect-ratio wings under tip effects
Kai Zhang, Shelby Hayostek, Michael Amitay +3
We perform DNS of flow over finite-aspect-ratio NACA 0015 wings to characterize the tip effects on the wake dynamics. This study focuses on the development of three-dimensional sep…
Randomized methods to characterize large-scale vortical flow network
Zhe Bai, N. Benjamin Erichson, Muralikrishnan Gopalakrishnan Meena +2
We demonstrate the effective use of randomized methods for linear algebra to perform network-based analysis of complex vortical flows. Network theoretic approaches can reveal the c…
Active Flow Control for Drag Reduction of a Plunging Airfoil under Deep Dynamic Stall
Brener D'Lélis Oliveira Ramos, William Roberto Wolf, Chi-An Yeh +1
High-fidelity simulations are performed to study active flow control techniques for alleviating deep dynamic stall of a SD7003 airfoil in plunging motion. The flow Reynolds number…
Revealing essential dynamics from high-dimensional fluid flow data and operators
Kunihiko Taira
We consider concepts centered around modal analysis, data science, network science, and machine learning to reveal the essential dynamics from high-dimensional fluid flow data and…
Modal Analysis of Fluid Flows: Applications and Outlook
Kunihiko Taira, Maziar S. Hemati, Steven L. Brunton +5
We present applications of modal analysis techniques to study, model, and control canonical aerodynamic flows. To illustrate how modal analysis techniques can provide physical insi…
