Ag. Knyazeva et Ve. Zarko, NUMERICAL-SIMULATION OF TRANSIENTS IN THE IGNITION OF 2-COMPONENT PROPELLANTS BY INTENSE HEAT FLUXES, Combustion, explosion, and shock waves, 29(3), 1993, pp. 266-269
An ignition model is developed for quasi-homogeneous propellants consi
sting of two perfectly mixed components which decompose independently
in the condensed phase and then react in the gas phase. The model desc
ribes the heat propagation in the condensed and gas phases as well as
the diffusion of components in the gas phase. The transition processes
from ignition to self-sustaining combustion under pulsed irradiation
are studied numerically for the simplest case of a monopropellant. It
is shown that the critical value of heat flux for stable ignition of m
onopropellant and the shape of the stable ignition peninsula in the ex
posure time - heat flux coordinates depend on the extinction criterion
.
