Equipment for Flow Diagnostics and Control

摘要

The DURIP grant enabled us to acquire a complete and powerful stereo Particle Imaging Velocity (PIV) system, equipment for experimentally implementing real-time feedback flow control, and all the necessary equipment for automatic control of the flow facilities at the Gas Dynamics and Turbulence Laboratory (GDTL). All of these equipment items enabled us to get detailed Ply measurements simultaneously with pressure measurements. We then used the techniques described in the rest of this report to obtain the first experimental results-based reduced-order model, and a controller based on the model. We have successfully implemented the controller with very encouraging results. The results presented in this report are based on two papers: one we presented in an AIAA conference last summer (Caraballo et al. 2005) and one we will present in another AIAA conference in early January 2006 (Caraballo et al. 2006).
