Based on detailed chemical kinetics, a combustion model for ADN was established first. The mechanism used consists of 33 species and 173 reactions. Results obtained from the model match the experimental data reasonably well. Then the model was carried out many times at various heat feedbacks from gas to condensed phase. And the calculations show that heat feedback is crucial to create a dark zone and determine the length of it.
