Abstract/Summary A two-parameter investigation into the effects oxygen enrichment has on combustion within a simplified scramjet engine was performed. The aim of this investigation is to quantify the influence of oxygen enrichment upon combustion efficiency over a range of fuelling conditions. This investigation utilised two-dimensional Reynolds-Averaged Navier- Stokes simulations at Mach 12 equivalent free stream conditions with multiple fuel equivalence ratios and enrichment percentages ranging between 0.8 – 1.4 and 0.0% - 20.0%, respectively. From these simulations it was found that oxygen enrichment produces notable gains in combustion efficiency due to both the presence of partially pre-mixed reactants and increases in the rate of mixing between reactant streams.
