Abstract

Thevolume-acceleration modelwasintroducedtodeterminetheinitialconditionsforthe motionofanunderwaterexplosionbubble.AsubcodewritteninFortranlanguagewasdevelopedto definetheinitialandboundaryconditionsforthefluidfield.Bycombiningthefiniteelementanalysis softwareMSC.Dytranandtheself-developedsubcode,thedynamicbehaviorsofthebubbleweresimulatedincludingoscillation, collapse,jetandsoon.Thecomputationalvolume-timecurvesofthe bubbleinthispaperaremoreconsistentwiththeexperimentalresultsthanthosebytheboundaryintegralmethod. Thedynamiccharacteristicsofthebubble,whichconsistofvolume,maximalradius, period,jetvelocity,andsoon,havecloserelationswiththechargemassandwaterdepth.Theobtainedcurvesarehelpfulforthecorrelativetheoryresearchandengineeringcalculation.
