Papers
On the role of adaptivity for robust laminar flow control
Nicolò Fabbiane,Bernhard Simon,Felix Fischer,Sven Grundmann,Shervin Bagheri,Dan S. Henningson +5 more
TL;DR: In boundary layer flows, one may reduce skin friction drag by delaying the onset of laminar-to-turbulent transition via the attenuation of small-amplitude Tollmien Schlichting (TS) waves.
Tip-vortex instabilities of two in-line wind turbines.
Vitor Kleine,Vitor Kleine,Elektra Kleusberg,Ardeshir Hanifi,Dan S. Henningson +4 more
- 01 Jul 2019
TL;DR: In this article, the hydrodynamic stability of a vortex system behind two in-line wind turbines operating at low tip-speed ratios is investigated using the actuator-line method in conjunction with the spectral-element flow solver Nek5000.
Complexity of localised coherent structures in a boundary-layer flow.
Taras Khapko,Yohann Duguet,Tobias Kreilos,Tobias Kreilos,Philipp Schlatter,Bruno Eckhardt,Bruno Eckhardt,Dan S. Henningson +7 more
TL;DR: In this article, numerically transitional coherent structures in a boundary-layer flow with homogeneous suction at the wall (the so-called asymptotic suction boundary layer ASBL) are investigated in a spanwise-extended domain that allows for robust localisation of all edge states.
Spanwise-coherent hydrodynamic waves around flat plates and airfoils
Leandra I. Abreu,Alvaro Tanarro,André V. G. Cavalieri,Philipp Schlatter,Ricardo Vinuesa,Ardeshir Hanifi,Dan S. Henningson +6 more
TL;DR: In this paper, the authors investigate spanwise coherent structures in the turbulent flow around airfoils, motivated by their connection with trailing-edge noise, and evaluate the dependence of such structures on the domain size, to ensure that they are not an artefact of periodic boundary conditions in small computational boxes.
Transient linear stability of pulsating Poiseuille flow using optimally time-dependent modes
TL;DR: In this article, Babee et al. explored the potential of using the optimally time-dependent (OTD) modes to extract information about both the transient and the time-asymptotic linear stability of pulsating Poiseuille flow.
