Internal Plenum Design and Testing for an Oscillatory Blowing Rotating Stall Suppression System
- View All
This paper presents results of an on-going effort to develop a new rotating stall suppression system. This system uses oscillatory blowing along the blade span on one or more airfoils in a row. The results presented herein focus on the flow characteristics of the internal plenum, and the performance of the oscillatory blowing system. A numerical simulation and an experimental investigation are being used to study the internal flow characteristics. The numerical simulation uses a Reynolds-averaged Navier-Stokes flow solver where the turbulence was modeled with the Shear Stress Transport model. The experimental setup developed for validating the oscillatory flow was developed to determine the relationship between the geometric configurations of the internal plenum and the resultant unsteady flow characteristics. The numerical simulations will be validated by data obtained from the experimental setup. Copyright © 2009 by the American Institute of Aeronautics and Astronautics, Inc.
