Abstract

Theinitialstageofdetonationproductsdrivingwaterwastestedbyashadowphotography techniquewithahighspeedrotatingframecamera.Thephotographsoftheinterfacebetweendetonationproductsandwaterwereacquiredclearly. TestwassimulatedbyusingLS-DYNA.Theresults shownumericalsimulationaboutpositionandvelocityofinterface,shockwavetrajectory,isaccordantwiththetest. Parametersacquiredcanbeusedintheimprovedtest.Accordingtothetheoretical analysis,themaximuminstantaneoustemperatureofwaterdrivenbydetonationproductisabout342 K,whichislowerthanthephasechangetemperatureattheexperimentalpressure.
