Relation between mass density of explosive detonation products and time is studied under three kinds of confinement conditions, i.e., no confinement, weak confinement, and rigid confinement by coupling of BKW code, JWL code and LS-DYNA program, respectively. Associated with HOM equation of state, explosion products temperature decaying with time is inferred, and theoretical method is proposed to calculate explosion products temperature of warhead. Results imply that temperature and its decaying rate in explosion products region are non-uniform. Confinement condition plays an important role in controlling of explosion products mass density and its temperature. Rigid confinement could postpone the decaying of the explosion products density and temperature, but the decaying time does not scale up in spite of the doubling of the shell thickness.
