Abstract
Instantaneous concentrations of reactive species are simultaneously measured in a planar liquid jet with a second-order chemical reaction urn:x-wiley:00011541:media:aic14610:aic14610-math-0001 to investigate the statistical properties of the chemical reaction rate and the validity of models which have been proposed for concentration correlation. The jet flow contains the reactant A, and the ambient flow contains the reactant B. The results show that the concentration correlation of the reactants makes a negative contribution to the mean reaction rate, and this contribution is important in the downstream direction. The concentration correlation changes owing to the chemical reaction. The effects of the chemical reaction on the concentration correlation change with the flow location and the Damköhler number. The concentration correlation predicted by the Toor's model and the three-environment model are compared with the experimental results. The results show that these models fail to accurately estimate the concentration correlation.

平面液体噴流中における2次化学反応の反応速度に関する実験的研究
2次化学反応を伴う平面液体ジェットにおいて、反応種の瞬時濃度を同時に測定し、化学反応速度の統計的性質と、これまで提案されてきた濃度相関のモデルの妥当性を検討した。その結果、反応物の濃度相関は平均反応速度に対して負の寄与をし、この寄与は下流方向で重要であることがわかった。この濃度相関は化学反応により変化する。化学反応が濃度相関に与える影響は、流れの位置とダムケーラー数によって変化する。Toorのモデルと3環境モデルによって予測される濃度相関を実験結果と比較した。その結果、これらのモデルは濃度相関を正確に推定できていないことがわかった。
