Abstract
Abstract : This project, aimed at an extensive study of the unsteady vortex dynamics and separation of pitching wings. Significant accomplishments were made in the project. These included extensive documentation of the 2-D velocity and vorticity field around a pitching NACA 0015 wing at a Reynolds number of 150,000, and extensive surface pressure and velocity data in the 3-D flow over a pitching swept wing of the same profile. The velocity data were obtained using the technique of Particle Image Velocimetry (PIV). The data have been used to understand the physics of 2-D and 3-D vortex dynamics separation in unsteady flows. The data have been archived carefully and will be made available to any interested user. This Final Technical Report gives a very brief summary of the Project activities.
