DURIP ADVANCED DIAGNOSTICS FOR EMBEDDED FLOW CONTROL FOR HIGH WORK / LOW REYNOLDS TURBINES (ADBFCONTUR)
Abstract
High-fidelity flow diagnostics are essential for developing physics-based reduced-order models and validation of computational fluid dynamics tools anchored on physics. In the AFOSR funded program FA9550-21-1-0053, we aim to optimize the use of unsteady blowing to prevent flow detachment. Experimentation with high-fidelity diagnostics is essential to assess the validity of the computational design tools and characterize instabilities conducive to flow detachment, a fundamental problem in aerodynamics. The proposed new Laser will enable PIV data at 40 kHz, with over 40,000 samples, i.e., 1Hz resolution. The selected Laser is a superior instrument, capable of delivering the necessary power of 6 mJ/pulse with minimal divergence and pulse width, essential to reduce blurring. In addition, it will reduce the amount of troubleshooting required before an experiment and drastically reduce the size of test campaigns with optical techniques, increasing the amount of data per test.
