High-resolution imaging of dissipative structures in a turbulent jet flame with laser Rayleigh scattering

High-resolution 2-D imaging of laser Rayleigh scattering is used to measure the detailed structure of the thermal dissipation field in a turbulent non-premixed CH 4 /H 2 /N 2 jet flame. Measurements are performed in the near field ( x / d = 5–20) of the flame where the primary combustion reactions i...
