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
  • Part of ZL3 Lab
