Abstract

Simulation of laser heat absorbing inclusions in a transparent matrix of explosive material is carried out. The inclusions are spherical particles with R0 radius ranging from 10-5 to 10-2 cm. The duration of the laser pulse varies from 10-9 to 10-3 s and allows investigating process in both adiabatic and quasi-stationary heating modes. It has been found that the duration of laser pulse affects the maximum heating temperature for particles with a specific radius. A remarkable thing is that the temperature drastically decreases if the absorption cross section and small size of inclusions are taken into account. It leads to heat reduction in a thermal center, which is formed nearby a small-sized inclusion, and shows strongly decreased reactive capacity of explosive decomposition.
