Abstract

Basedonthecalculationsonthepowderedaluminumpressureandtemperaturerelaxation timesinthedetonationzone,theconventionalCJmodelwasimprovedtoproposeanew multiphase flow modelbyconsideringthemultiphasedetonationproductsaswellasthethermaldisequilibriumin them.Theproposedmodelwasappliedtocalculatethedetonationvelocitiesofseveralaluminizedexplosives. Thecalculatedresultswerecomparedwiththeexistentexperimentalones.Andthecorrespondingerrorislessthan2%. Sothecalculatedresultsbythenew modelarebetterthanthoseby theconventionalCJmodel.
