Advanced Imaging Techniques for Flows Past Swept Wings.
Abstract
A major goal of this investigation is to develop a high-speed laser scanning technique for characterizing the instantaneous topology and vorticity distributions over crossflow planes of a delta wing undergoing defined rolling motion at a given angle of attack. By using new types of image construction techniques, it will be possible to determine the central physics of the three-dimensional flow structure in both the early stages of vortex breakdown, as well as in fully-stalled regions along the wing. In turn, these observations provide a basis for physically interpreting the unsteady loading on the wing. Central to this interpretation are topological representations of the streamline patterns, which provide a quantitative framework for classifying the flow patterns.
