乱流火炎のフラクタル次元の理論的評価〔熱工学, 内燃機関, 動力など〕

The authors evaluated the Fractal dimension on turbulent premixed flame based on HTA (Hyperbolic Tangent Approximation) model for fully developed turbulent field. Main results are as follows : (1) The fractal dimension evaluated without a effect of flame stretch is 2.67. (2) The fractal dimension evaluated with the effect of flame stretch is 2.33, This value is in good agreement with experimental data.
