Network-based characterization of unsteady fluid flows
Support: ARO, AFOSR
This novel work aims to uncover the interaction network in fluid flows.
Collaborator: S. Brunton (U Wash)
Active flow control of separated flows
Support: AFOSR (YIP)
We investigate the effects of fundamental flow control inputs on suppressing stall for a canonical airfoil with LES and global stability analysis.
3D control of high-speed cavity flow
Active flow control and global stability analysis are utilized to reduce the velocity and pressure fluctuations in open cavity flows.
Collaborators: L. Cattafesta (FSU), L. Ukeiley (UF)
Turbulent flow modification with thermoacoustics
This project studies the possible use of thermoacoustic actuators to modify the characteristics of turbulent shear flows.
Attenuation of wing tip vortex
This project examines the use of instability based control of wing-tip vortex.
