Intheexperiment,moltenmaterialjetisinjectedintowatertoexperimentallyobtainthevisualizedinformationofthefragmentationandboilingphenomenaduringPAHRinCDA.Theexperimentshowsthatthebreakupofthemoltenmaterialintofinefragmentsisobservedatthefront,sideandmiddlepartofthejetduringveryshorttimeinterval.Thedistributedparticlebehaviorofthemoltenmaterialjetisobservedwithhigh-speedvideocamera.AndthevisualdataisanalyzedwithParticleImagingVelocimetry(PIV). Theexperimentalresultsarecomparedwiththeexistingtheories.Consequently,themarginalwavelengthonthesurfaceofawaterjetisclosetothevalueestimatedbasedontheRayleigh–Taylorinstability.Moreover,thefragmenteddropletdiameterobtainedfromtheinteractionofmoltenmaterialandwaterisclosetothevalueestimatedbasedontheKelvin–Helmholtzinstability.
