Abstract

Abstract

The conservation equations describing the movement of the plasma in the laser-supported detonation process are numerically calculated with the space-time conservation element and solution element method. The distributions of the pressure, the density, the temperature, the velocity and the absorption coefficient of the plasma at different time interval are given. The characters of the evolving plasma with different initial density are compared. It is concluded that, the absorption of laser is larger when the plasma has larger initial density. The laser energy can be better coupled to the target by modifying the initial density of the plasma, the duration of the laser pulses and the pulse interval.
