Ammonium dinitramide (ADN) combustion model with detailed gas phase reactions

A numerical calculation model with detailed gas phase reactions was developed to study the physical and chemical processes involved in ammonium dinitramide (ADN) combustion. The model was based on the conservation equations of mass, species concentration and energy, and takes into account finite-rate chemical kinetics. At last, the equation of state for a multicomponent system was employed to close the equations. A chemical kinetics scheme, containing totally 34 species and 165 reactions, was established and employed in the model. The model was applied to predict species mole fractions and temperature profiles in ADN gas phase flame at 0.3 MPa. The agreements between calculation results and experimental data are very well. The results show that the model can predict ADN gas phase combustion wave accurately.
