Ethene/nitrous oxide mixtures as green propellant to substitute hydrazine : Reaction mechanism validation

Naumann, Clemens ; Kick, Thomas ; Methling, Torsten LU ; Braun-Unkhoff, Marina and Riedel, Uwe (2020) In International Journal of Energetic Materials and Chemical Propulsion 19(1). p.65-71
Abstract

Reaction mechanism validation for nitrogen-diluted ethane/nitrous oxide mixtures at stoichiometric conditions has been performed using ignition delay time measurements at p = 1, 4, and 16 bar as well as laminar flame speed measurements at p = 1 and 3 bar. The predictive capability of the public domain mechanism GRI 3.0 was improved considerably by adapting some reactions within the nitrogen subsystem and optimizing the most sensitive reactions with respect to selected optimization targets (i.e., ignition delay time and selected laminar flame speed measurements) within the published error bounds.
