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…
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…
Randomized resolvent analysis
Jean Hélder Marques Ribeiro, Chi-An Yeh, Kunihiko Taira
Performing global resolvent analysis for high-Reynolds-number turbulent flow calls for the handling of a large discrete operator. Even though such large operator is required in the…
