Numerical Simulation of Solid-Phase Ignition of Metallized Condensed Matter by a Particle Heated to a High Temperature

摘要

Numerical simulation of the ignition of a composite propellant by a single “hot” particle of metal is carried out in the framework of the solid-phase model of ignition. The dependences of the ignition lag time for a metallized condensed matter on the initial temperature of a local energy source are determined. Close agreement of the obtained theoretical results with the known experimental data is found.
