Development of ADN Monopropellant Combustion Model with Detailed Gas-Phase Kinetics Mechanism
A numerical gas-phase combustion model has been developed to study the physical and chemical processes involved in ADN combustion. The model is 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 multi-component system is employed to close the equations. A detailed chemical kinetics scheme, which is optimized from mechanisms in references, involving 34 species and 165 reactions, is employed to describe the combustion wave in gas phase. Excellent agreement between predicted and measured temperature profile and species concentration profiles have been obtained at 0.6 MPa. It indicates that current model can predict ADN monopropellant gas phase combustion wave accurately. Comparison shows the current gas phase kinetics mechanism is the best one compared to the counterparts in references.
