Visualization of Flow Control Devices (VGJs) for Low Pressure Turbine Separation Control Using Stero PIV
Abstract
An AFOSR-sponsored collaborative effort in low-pressure turbine (LPT) flow control is currently underway to capitalize on recent laboratory successes using vortex generating jets (VGJs). AFRL/PRTT, the University of Arizona, and Brigham Young University (BYU) are all players in this effort to enhance the understanding of the effect of VGJs on separating LPT boundary layers. AFRL/PRTT has the design task (under Drs. Richard Rivir and Rolf Sondergaard) to integrate flow control strategies into the Air Force's jet engine inventory. To make the transition of VGJs from the laboratory to the design process will require a greatly improved understanding of the fundamental physics, so that accurate models can be developed and incorporated into LPT design codes. Dr. Hermaun Fasel (University of Arizona) has an AFOSR grant to develop computational models as building blocks for this design integration process. The necessary experimental data to validate these models is being obtained from wind tunnel testing at BYU (Dr. Jeffrey Bons as PI).
