Planar Laser-Induced Fluorescence Scalar Measurements in a Turbulent Jet
The planar laser-induced fluorescence (PLIF) technique has been used to measure the concentration of a passive molecular tracer (biacetyl) in a turbulent axisymmetric nitrogen jet. The emitted light was recorded using two low noise, high dynamic range CCD cameras. The acquired images were corrected for experimental artifacts and statistically analyzed. Results are presented for mean concentration, RMS concentration fluctuations, scalar dissipation, and cross-section centered means.
