Abstract

Theignition-growthreactivemodelandadesensitizingmodelwereintroducedintotheselfdevelopedtwo- dimensionalmulticomponentEulerianelastic-plastichydrodynamicscode(MEPH2Y), respectively.Numericalstudieswerecarriedoutonsomedetonativephenomenaincludingtheshock ignition,thediametereffectandtheformationofthedeadzone,withtheaidoftheadaptivemeshrefinementtechnique. Thenumericalresultsshowthatthecomputationcansimulatethemajorcharacteristicsoftheplanardetonationwaves, suchasthedetonationwavespeed,CJstate,vonNeumann spikestateandsoon.Andthediametereffectsoftheexplosivescanbesimulatedcorrectly.Under theconsiderationofthedesensitizingreactivemodel,thedeadzoneformationoftheinsensitivehigh explosivescanalsobereproduced.
