Effects of Chamber Width on H2/Air Rotating Detonations

International Journal of Aerospace Engineering, 2020
To get the effects of chamber width on the H2/Air rotating detonations, several models with different widths have been investigated. By using a one-step chemical reaction model, one wave is induced in all models.

Early ultraviolet emission in the Type Ia supernova LSQ12gdj: No evidence for ongoing shock interaction [PDF]

, 2014
We present photospheric-phase observations of LSQ12gdj, a slowly-declining, UV-bright Type Ia supernova. Classified well before maximum light, LSQ12gdj has extinction-corrected absolute magnitude $M_B = -19.8$, and pre-maximum spectroscopic evolution ...

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。
