| Abstract: | The numerical simulation on gas-liquid two - phase flow and mix in the agitation tank of the existing agitator and the optimized agitator in a smelting plant were carried out by means of Computational Fluid Dynamics （CFD） software Fluent, in which the ve- locity distribution, local gas volume fraction and agitation power in the agitation tank of two kinds of agitators were contrasted. The calcula- tion results show that the stirring and mixing effects and gas diffusion of the optimized agitator are superior to those of the existing agitator, and the agitation power basically remains unchanged. |
| Keywords: | numerical simulation agitation tank gas - liquid two - phase Computational Fluid Dynamics （CFD） |
