Fluid flow and mixing process in a bottom stirring electrical arc furnace (EAF) with the single-and multiplug are experimentally and numerically studied. A homogeneous fluid with a spatially variable density is used to model the gas–liquid flow. k– e turbulence model is employed to calculate the effective viscosity. The five layouts are selected to examine the mixing times. The mixing time is defined as the function of the diameter, number, location of plugs and the tracer injection point. The results show that the variation of mixing time is not obvious with the increasing of plug diameter, but the stirring efficiency is getting better when plug number is increased and distributed in deep and off-central region in vessel. This is because the angular velocities occur and the more stirring energy is obtained in such layouts.
