Insights into Leading Edge Vortex Formation and Detachment on a Pitching and Plunging Flat Plate
Johannes Kissing, Jochen Kriegseis, Zhenyao Li +3
The present study is a prelude to applying different flow control devices on pitching and plunging airfoils with the intention of controlling the growth of the leading edge vortex…
Delaying Leading Edge Vortex Detachment by Plasma Flow Control at Topologically Critical Locations
Johannes Kissing, Bastian Stumpf, Jochen Kriegseis +2
Flapping wing propulsion offers unrivalled manoeuvrability and efficiency at low flight speeds and in hover. These advantages are attributed to the leading edge vortex developing o…
Sinusoidal-gust generation with a pitching and plunging airfoil
Nathaniel J. Wei, Johannes Kissing, Cameron Tropea
The generation of uniform, periodic gust disturbances in an experimental context is demonstrated using a single oscillating airfoil. A pitching and heaving symmetric airfoil is sug…
Insights into the Periodic Gust Response of Airfoils
Nathaniel J. Wei, Johannes Kissing, Tom T. B. Wester +6
The unsteady lift response of an airfoil in a sinusoidal gust can be modeled by two transfer functions: the first-order Sears function and the second-order Atassi function, albeit…
