Experimental and numerical investigations of the dry-low-NOx hydrogen micromix combustion chamber of an industrial gas turbine
TL;DR: In this article, the authors apply and compare different combustion models for the characterization of the micromix flame structure, its interaction with the flow field and its NOx emissions, and reveal great potential for the successful application of numerical flow simulation to predict flame structure and NOx emission level of micromixed hydrogen combustion, help understand the flow phenomena related with the micmmixing, reaction zone and NOix formation and support further optimization of the burner performance.
