Abstract
TodevelopanignitionandgrowthreactionflowmodelforHNS-Ⅳexplosive,cylindertests
wereconductedonHNS-ⅣexplosiveandtheexpansionprocessesofthecoppercylinderwallswererecordedbyaGSJhighspeedrotatingmirrorcamera,
andparticlevelocitiesattheinterfacebetween
HNS-ⅣexplosiveandLiFwindowweremeasuredwithlaservelocityinterferometry(VISAR).The
correspondingnumericalsimulationswerecarriedoutbyANSYS/LS-DYNA,respectively.TheJWL
equation-of-stateparametersforunreactedexplosivewerefittedtotheavailableshockHugoniotdata.
Andbycombiningtheexperimentalresultsandnumericalsimulations,theJWLequation-of-stateparametersfordetonationproductweredetermined,
aswellasreactiverateparametersforreactionignitionandgrowthin

growthreactionflow modelcanbeusedtopicturethereactionprocessofHNS-Ⅳexplosive,andthe
numericallysimulatedresultscanagreewiththeexperimentalones.
