摘要

针对含有密集垂直列管束内构件的气液鼓泡塔

在两相Euler二维轴对称k-ε模型中

分别考虑气相和液相受到的列管阻力。通过引入相应的动量源、湍动源以及耗散源建立带列管内构件的鼓泡塔二维CFD模型。模型能清晰、准确地描述带列管束鼓泡塔中气液流动的特征:"烟囱效应"以及分布器影响区延长。计算得到的气含率以及液速的二维分布在宽泛的表观气速(0.12～0.62 m·s-1)范围内与实验值相符。

Abstract

For gas-liquid bubble column with dense vertical bundle internals

the resistance force of bundles on gas and liquid phases was taken into account in the two-phase Euler axisymmetric k-ε model. By introduction of corresponding momentum source

turbulence source and dissipation source

a 2-D CFD model of bubble column with bundle internals was established. The model could clearly and accurately demonstrate the features of gas-liquid flow in bubble column with bundles: "funnel effect" and extension of sparger zone. The calculated two-dimensional distributions of hold-up and liquid velocity agreed with experimental data within a wide range of superficial gas velocity (0.12—0.62 m·s-1).
