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…

Control of long-range correlations in turbulence
Kevin P. Griffin, Nathaniel J. Wei, Eberhard Bodenschatz +1
The character of turbulence depends on where it develops. Turbulence near boundaries, for instance, is different than in a free stream. To elucidate the differences between flows,…
