Flame Anchoring of an H2/O2 Non-Premixed Flamewith O2 Transcritical Injection

The article is devoted to the analysis of flame anchoring mechanism in test case MASCOTTE C-60 RCM2 on supercritical hydrogen/oxygen combustion at 60 bar, with transcritical (liquid) injection oxygen. simulated by means in-house parallel code HeaRT three-dimensional LES framework. cubic Peng–Robinson equation state its improved translated volume formulation assumed. Diffusive mechanisms and transport properties are accurately modeled. A finite-rate detailed scheme involving main radicals, already validated for high-pressure H2/O2 combustion, adopted. flow analysed terms temperature, hydrogen oxygen instantaneous spatial distributions, evidencing effects vortex shedding from edges injector separation stream divergent section tapered topology. Combustion conditions characterised looking equivalence ratio compressibility factor distributions.
