DOI: 10.1016/j.actaastro.2020.04.037
Abstract: Abstract H2/air supersonic mixing layers were calculated with different splitter plates thickness. The accumulation of OH radicals between the most reactive and stoichiometric mixture fraction causes the corresponding change of reactions. With the increase of… read more here.
