Capturing multiscale interactions in fluid flow via Lagrangian coherent structures and modal analysis
Morgan R. Jones, Charles Klewicki, Oliver Khan +2
We consider the relationship between Eulerian modal decompositions and Lagrangian coherent structures (LCSs). The model sensitivity framework developed by Kaszás and Haller (2020)…

Aerodynamic Control of Laminar Separation on a Wall-Bounded Airfoil at Transitional Reynolds Numbers
Charles Klewicki, Ari Schenkman, Geoffrey Spedding
Experiments were conducted in a low-turbulence wind tunnel to investigate the efficacy of localised acoustic forcing upon the dynamics and stability of the flow on a cambered, wall…

The Footprint of Laminar Separation on a Wall-Bounded Wing Section at Transitional Reynolds Numbers
Charles Klewicki, Bjoern F. Klose, Gustaaf B. Jacobs +1
When a chordwise Reynolds number (Re) falls below about the performance of wings and aerodynamic sections become sensitive to viscous phenomena, including boundary layer sep…
