摘要：
We study the interplay between translational and reaction kinetics in a simplified model of a steady detonation front induced by a threshold exothermic reaction, based on the Direct Simulation Monte Carlo (DSMC) method. The reaction is modeled as a single step, irreversible, threshold reaction with Arrhenius kinetics. Results show that the nonequilibrium character of the velocity distribution function in the shock front modifies substantially the kinetics of the reaction and the overall profile of the reaction zone.
