چکیده انگلیسی
This paper, concentrates on a three-dimensional (3D) computational fluid-dynamics (CFD) model for coal combustion and electrode radiation inside an electric-arc furnace (EAF). Simulation of the melting process includes combustion reactions of coal particles and radiation from electrodes. Particle surface and gas phase reactions were used to predict injected coal particle combustion. The predicted temperature distributions are realistic because of the inclusion of combustion reactions and radiation models together. The CFD model provided detail information for the coal particles combustion and radiation interactions phoneme inside the electric-arc furnace. The cooling process of the EAF walls were considered in the CFD model hence heat losses from the walls have been found higher than the earlier studies. Results showed that CFD simulation can efficiently be used to develop and investigate EAF in design phase.
