Properties of turbulence in turbulent diffusion flames

Abstract Measurements of flow velocities and the statistical properties of turbulence such as turbulence intensities, probability density function, autocorrelation, length scales, and power spectrum are carried out by laser Doppler velocimeter, along with the measurements of gas temperature and gas species concentration in turbulent jet flows with and without flame. Distinctive features of turbulence properties due to existence of flame are pointed out.
