Combustion and Laser Diagnostics Laboratories

Combustion and Laser Diagnostics Laboratories

​Various state-of-the-art diagnostic equipment is available for use by all center members.  The Center has a very significant investment in both coherent and incoherent laser-based diagnostic techniques for measuring major and minor species, velocity, temperature, droplet size and size distribution, and soot volume fraction.  In addition to world-class Analytical Chemistry and Visualization Core labs, the center has its own analytical chemistry capability for extractive sampling measurements of permanent gases and hydrocarbon species up to multi-ring PAHs.

Facilities

  • Soot Diagnostics Brand: Expla,
    Model: NL 909 -5-SH
    Soot Diagnostics Measurements of soot volume fraction, soot morphology and soot particle size by using laser extinction method (LEM), multi-angle elastic light scattering (MAELS) and laser-induced incandescence (LII)
  • PLIF – Planar Laser Induced Fluorescence Study Brand: Continuum,
    Model: PL9010 DL
    PLIF – Planar Laser Induced Fluorescence Study (PLIF) is an optical diagnostic technique widely used for flow visualization and quantitative measurements. PLIF has been shown to be used for velocity, concentration, temperature and pressure measurements.
  • 10 Hz - PIV Lab and Flow visualizations Brand: Litron,
    Model: Nano PIV
    10 Hz - PIV Lab and Flow visualizations Particle image velocimetry (PIV) is an optical method of flow visualization used to obtain instantaneous velocity measurements and related properties in fluids as well as providing instantaneous velocity vector measurements in a cross-section of a flow. This technique being a non-intrusive one, allows the application of PIV in high speed flows, boundary layer studies of fluids.
  • High speed OH-PLIF system Brand: Litron,
    Model: LDY-300
    High speed OH-PLIF system Simultaneous application of PIV and LIF techniques contributed to better understanding of turbulence–flame interaction, including flame extinction phenomena in turbulent non-premixed jet flames, low-swirl turbulent premixed flames, flame surface density, flame front curvature and turbulence statistics in lean premixed flames.
