説明
The authors discuss in detail the various heat transportation mechanisms existing in turbulent diffusion flames by use of spectral analyses. Space and time-resolved structures of turbulent diffusion flames were analyzed by two-point laser Rayleigh spectroscopy (LRS) which did not directly interfere with the combustion media during measurement. The turbulent diffusion flame structures were divided into 4 regions based on the characteristics of their spectral analysis of time-dependent temperature signals. In order to discuss the macroscopic heat transportation mechanism, the coherent function from cross and power spectral functions at Region I∼IV was analyzed. From these analyses, the following diffusion characteristics at each region were revealed. Region I : three-dimensional diffusion mechanism (x-, r-, z-axes), Region II : one-dimensional diffusion mechanism (z-axis), Region III : two-dimensional diffusion mechanism (x-, z-axes), Region IV : no specific diffusion mechanism.
