要約

A method is proposed to consider the turbulence-radiation interaction in the analysis of a multiphase diffusion flame. Application is made to study the reaction of a halogen gas jet submerged in an alkali liquid fuel bath. The analysis makes use of a k-ε-g turbulence model, a local homogeneous two-phase model, a chemical equilibrium combustion model, a probabilistic approach and a radiation model compatible with mixture fraction fluctuation. The equilibrium state relationships for instantaneous properties, required for mean scalar property predictions and structure analysis of the reacting jet, have been generated. The energy equation containing the radiative source term has been solved simultaneously with the Favre -averaged transport equations. Numerical results are presented for the specific reactants -chlorine gas as oxidant and liquid sodium as fuel. In comparison to the adiabatic case in which thermal radiation is neglected, the results reveal that thermal radiation greatly affects the plume envelope and the turbulent flame structure.
