摘　　要：利用计算流体力学软件FLUENT6.2对低气速下的鼓泡塔和气流内循环式反应器内的湍流两相流动进行了二维非定常模拟,两相流模型为欧拉模型(双流体模型),湍流模型为标准k-ε模型。将两种反应器的模拟结果进行了比较,结果显示,由于气升式反应器内存在导流筒,使得两种反应器内的两相流动特性有较大的不同。对此进行了定量的研究,并与相关文献的研究结论进行了对比分析。Two-dimensional unsteady simulations of a bubble column and an internal airlift loop reactor at low gas flow rate are presented. The simulations are based on an Euler-Euler two-phase model and a standard k-ε turbulence model. Because of the draft tube in an internal airlift loop reactor, the flow patterns are quite different in these two： reactors. The differences between them are studied quantitatively. The numerical results of the two reactors are compared with those in previous references.
