摘　　要：利用计算流体力学(CFD)软件Fluent,对某冶炼厂现有搅拌器和优化后搅拌器搅拌槽内的气液两相流动和混合进行了数值模拟,对比了两种搅拌器搅拌槽内的速度分布、局部气含率和搅拌功率。计算结果表明,优化后的搅拌器搅拌混合效果和气体分散优于现有搅拌器,且搅拌功率基本不变。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.
