Abstract

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