Abstract

A model is presented for the turbulent combustion of CO/H₂-air Mixtures at gas turbine conditions. The model takes account of heat losses. The conversion of CO to CO₂ and of H₂ to H₂O, as well as the non-equilibrium intermediate species concentrations are determined by two reaction progress variables and two other scalar variables. The initially available fuel concentration is expressed by a fuel mixing variable. The heat loss effect on the enthalpy is described by a scaled enthalpy variable. The modelled turbulent source terms in the transport equations for the scalar variables are discussed. Three cases of a turbulent CO/H₂ diffusion flame with heat loss and chemical super-equifibrium of intermediate species are presented.
