Abstract

Anexperimentaldevicewasdesignedtoinvestigatetheprocesscharactersofliquidexplosion dispersion.Theliquiddispersionprocesswasrecordedbyusingahigh-speedcamera.Theseveralcasesweretakenintoaccount, whichincludeddifferentexplosivequantitiesanddifferentviscosityliquids. Itisfoundthatassoonasthecontainerisbroken,theliquiddispersesthroughthesplits.Inthe caseofsmallexplosivequantity,theliquiddispersionpatternlookslikeanintercrosstree,then breaksintosmalldroplets.Inthecaseoflargerexplosivequantity,theliquiddispersionpatternlooks likeanannulus.Theliquidannulusconsistsofsmalldroplets,vaporizedliquid,atomizedliquid,or liquidsheet,ligamentsandbigdroplets,dependingontheviscosityoftheliquid.Thewidthofthe liquidannulusincreasesinthedispersionprocess,andtheliquidsheet,ligamentsandbigdropletscan breakintosmalldroplets.
