A 1-D numerical compressible fluid model was created to simulate self-sustained decomposition of nitrous oxide. The model uses a preheated, thermally conductive metal foam as an alternative to catalysts. An extensive parameter study was conducted to help understand thermal and fluid effects on steady-state decompositions. Using a copper metal foam, steady-state solutions simulated successful nitrous oxide decomposition, with an exit gas temperature around 1345 K. Simulations were extended to other high-temperature metal foams with different thermal conductivities and melting points. Modeling flow rate conditions more representative of current monopropellant thrusters required scaling of the decomposition chamber in order to be self-sustaining.
