Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Rotational Temperature of OH Radicals in Detonation Waves

The Journal of the Society of Chemical Industry, Japan, 1962
前報の装置を用いて初圧60mmHgのC2H2+H2+2O2の安定爆轟波について,OH基の吸収スペクトルを撮影した。得られたOH基の2Σ+→2π帯,O-O遷移,R2分岐における吸収線を通常の基本法を用いて解析することにより,OH基の回転温度を得ることが出来た。爆轟波面背後の各場所における回転温度は爆発論より計算した気体温度より,平均して392°K低いが,スペクトル解析の際Jamesにより提出された振動回転相互作用の補正を用いると,両者はよい一致を示した。

Influence of fuel inhomogeneity on detonation wave propagation in a rotating detonation combustor

Shock Waves
AbstractRotating detonation combustor (RDC) is a form of pressure gain combustion, which is thermodynamically more efficient than the traditional constant-pressure combustors. In most RDCs, the fuel–air mixture is not perfectly premixed and results in inhomogeneous mixing within the domain.
