Influence of Nozzle Design on the Performance of a Partial Combustion Lance: A CFD Study

This paper presents a computational fluid dynamics (CFD) simulation of a partial combustion lance (PCL) aiming to evaluate the effect of nozzle design on its performance. Four turbulence models, namely, standard k-ε (SKE), realisable k-ε (RKE), renormalised (RNG) k-ε and Reynolds stress model (RSM)...
