Interaction between an Airfoil and a Streamwise Vortex,

Abstract

The tip of a finite-span airfoil was used to generate a streamwise vortical flow, the strength of which could be varied by changing the incidence of the airfoil. The vortex that was generated traveled downstream and interacted with a second airfoil on which measurements of lift, drag, and pitching moment were made. The flow field, including the vortex core, was visualized in order to study the structural alterations to the vortex resulting form various levels of encounter with the downstream airfoil. These observations were also used to evaluate the accuracy of a theoretical model. (Author)
