ZL3 Optical Diagnostics
High-Repetition-Rate Laser Diagnostics
- Particle Imaging Velocimetry (PIV) at 5-10 kHz for velocity fields
- OH Planar Laser-Induced Fluorescence (PLIF) at 5-10 kHz for reaction fronts
- Simultaneous PIV/OH PLIF at pressures up to 20 bar
- Pulse burst laser system for 100 kHz PIV, PLIF on order - $500,000 Purdue internal money
- Stereo PIV for three-component velocity measurements just demonstrated
- Simultaneous Mie scattering/fuel PLIF for visualization of distributions of fuel liquid and vapor: images acquired at 5 kHz for RR injector are shown below – black indicates liquid fuel from Mie scattering
