Interaction of vortex streets with a downstream wing
Burak Buda Turhan, Zhijin Wang, Ismet Gursul
Abstract
A wing submerged in the wake of an upstream airfoil experiences periodic forces. The frequency and the amplitude of the airfoil oscillations produce vortex streets of varying wavelength and circulation. The amplitude of the lift coefficient of the wing depends on a single wake parameter, which is the Strouhal number based on the amplitude of the upstream airfoil.
