The present study is focused on the modeling and simulation of the combustion of methane with oxygen at high pressure, i.e. in the supercritical regime. In this configuration, a priori no interface between the two propellants can be discerned. However, the modeling requires particular attention to high-pressure thermodynamics and non-ideal transport. Triple flames develop at different locations in the flow showing reactive island structures either in the methane or oxygen stream. Such behaviors are recovered by LES.
