Turbulent Boundary Layer Features via Lagrangian Coherent Structures, Proper Orthogonal Decomposition and Dynamic Mode Decomposition

Naseem Ali, Murat Tutkun, Raúl Bayoán Cal

High-speed stereo PIV-measurements have been performed in a turbulent boundary layer at Re${}_{\theta }$ of 9800 in order to elucidate the coherent structures. Snapshot proper orthogonal dec…
