Abstract

Basedonthefactthatinanexperimentaldevicefilledwithexplosiveandfluoride,theexplosionofthecentralexplosivecoulddispersethefluorideoutofthedevice, thenthefluoridewouldintenselyreactwiththeliquidintheconfinedcontainerandreleaseplentifulenergy, threeexperiments withdifferentexplosiondepthswerecarriedoutinsmall-scaleconfinedcontainerstoevaluatethedamagepowerofthisdeviceaccordingtotheoverpressure- impulsecriterion.AndtheTNTequivalent massofthisdevicewascalculated.Theexperimentwiththeexplosiondepthof1.2mwasnumerically simulatedbyusingtheexperimentaldata.Themaximumdispersalvelocityofthetopcoverobtained bysimulationisclosetotheexperimentalresult.Itdisplaysthatthegivenevaluationmethodisfeasible.
