摘　　要：利用计算流体力学(CFD)软件,采用标准k-ξ紊流模型,分析了非稳态情况下双层涡轮搅拌槽内流体的三维紊流流场、紊流动能及能量耗散,讨论了不同桨间距对流场、紊流动能及能量耗散的影响。In the condition of non-steady state, three-dimensional turbulent flow, kinetic energy and energy dissipation were calculated with k- model by means of CFD soft. The effects of space between two impellers on flow, kinetic energy and energy dissipation were discussed.
