摘要 Three kinds of application of nonlinear fractal theory in the turbulent combustion werediscussed, which included the multiscale measurement, the measure analysis and the correlative dimension of chaotic attractors in temperature time series signals. This work not onlyrevealed the spatial fractal character in combustion, but also acquired the correlation andtemporal scale of the turbulent flunctuation.
