乱れのスペクトルを考慮した乱流燃焼速度モデル : 理論混合気の場合

概要

論文の詳細を見る
A formerly proposed spectral model of turbulent mass burning velocity is refined in regard to the following three points: (1) a small modification of the characteristic spectrum of mixture, (2) consideration of varying turbulence spectrum shape with turbulence intensity and (3) a new idea of the upper limit of the integral which is strongly related to the small-scale structure of turbulent flame. Predictions of turbulent mass burning velocity were made by this spectral model. The predicted velocities were compared with the measured turbulent mass burning velocities, where laminar burning velocity, laminar flame thickness and turbulence intensity were varied extensively and independently with each other under a stoichiometric mixture condition. As the result of comparison, the quantitative accuracy of the refined model was confirmed.
