In order to discuss the influence of turbulence on turbulent burning velocity and to compare the experimental results of many workers with each other quantitatively, it is necessary to represent a turbulent field using the parameters with general definition. Some arbitrariness was unavoidable in the definition of turbulence parameters especially in the study of turbulent combustion in a closed bomb, in which the turbulence was measured usually with a hot-wire anemometer. A procedure for the analysis of a turbulent field of any turbulence intensity by processing the DC and AC indication of a squared anemometer output signal of the effective cooling velocity, is described and the results of the turbulence parameters in a closed bomb, such as intensity, temporal scale and spatial scale, in comparison with those by conventional method, are shown in this paper.
