Reaction-rate based modeling of MILD Combustion in a cyclonic burner

MILD combustion is a regime in which oxidation reactions occur without a deflagrative flame front. CFD plays a key role in the successful introduction of such a concept for several industrial applications. In this framework, this work aims to improve the knowledge about the modeling requirements of such a regime in a scale-bridging burner, which ensures MILD combustion condition through an internal recirculation of flue gases and thus mimics industrial devices. Different dilution conditions are simulated through reactive FANS simulations, by implementing modifications proposed in literature of the Eddy Dissipation Concept model for the treatment of the turbulence-chemistry interaction.
