Abstract

Inordertoinvestigateignitioncharacteristicofenergeticmaterialsradiatedbylaser,agasphasereactionmodelwasestablishedusingdetailedchemicalkinetics. Inthemodel,45speciesand 232reactionstepswasusedtodescribegasphasemechanism.Thenthemodelwasusedformodeling theprocessoflaser-inducedignitionofRDX.Temperaturedistributionsinbothcondensedandgas phasewereobtainedtoanalysetheprocessofignitionofRDX.MoleFractionsofmainspecieswere presentedtoshowthechemicalreactionprocessinthegasphase.Thecalculatedignitiondelaytimes areconsistentwiththeresultsinliteratures.
