Behaviors of Coherent Flow Field with Various Shrouding Nozzles Arrangement

摘要

In this paper, the effect of shrouding nozzles arrangement on flow field and stirring ability of coherent jet had been analyzed under two kinds of ambient temperatures. Compared with axial velocity and total temperature distribution in combustion experiment, the Eddy Dissipation Concept (EDC) model and detail chemical kinetic mechanism were adopted to represent the combustion reactions of the O_2-CH_4 jet flame in numerical simulation. Based on the experimental results of the water experiments and the numerical simulations, the coherent jet with different shrouding nozzles arrangements was used to research the application effect in a 100 t electric arc furnace, and then an optimum arrangement was confirmed.
