Formatted abstract
An investigation into the mixing characteristics of porous injection into a supersonic crossflow with oxygen enrichment was undertaken. It was found that increasing oxygen enrichment to levels of 10% and 20% resulted in increasing oblique shock angles, increased penetration of fuel into the mainstream flow and achieved better local mixing than un enriched cases. Further unexpected observations found that as the equivalence ratio was increased from 1.0 to 1.25, the mixing efficiency decreased. It was also observed that detached shocks were formed in the x-z plane, challenging what has previously been seen with porous injection. It has been proposed that further research be undertaken to further understand the unexpected phenomenon.
