Non-intrusive, spatially and temporally resolved temperature measurements in turbulent flames, premixed and non-premixed, using laser Rayleigh scattering are reported. It is demonstrated that through judicious design of experiments, laser Rayleigh scattering can be used to measure temperature (or concentration) at a data rate, and hence frequency response, DC-15 kHz, that is undemonstrated by any other present day laser based technique. Two demonstrations of laser Rayleigh thermometry are described: a turbulent premixed flame, and a turbulent jet diffusion flame. The turbulent jet diffusion flame uses a novel mixture of hydrogen and methane as fuel. This fuel mixture permitted the first laser Rayleigh thermometry in turbulent non-premixed flames. 35 refs.
