摘要

在有机玻璃制成的二维鼓泡床(0.20m×0.02m×2.00m)内，采用摄像法对空气－自来水的气液两相体系的气泡尺寸分布进行了考察。以商业计算流体力学软件ANSYS CFX 10.0为平台，在双流体模型的基础上，采用k-ε湍流模型和GRACE曳力模型对气液鼓泡床内流体动力学行为进行了多相流CFD数值模拟。结果表明 MUSIG(Multiple Size Group)模型实现了对多气泡体系内气泡尺寸分布特性的考察，气泡尺寸分布的模拟结果与实验结果吻合得较好，从而说明了考虑了气泡聚并破碎的MUSIG模型能很好地反映出鼓泡床内气泡尺寸分布特性。

Abstract

Bubble behavior was observed by using high-speed digital camera in a two-dimensional rectangular bubble column of 0.20 m（width）× 0.02 m（thickness）× 2.00 m（height）.Air and water were used as gas and liquid phases，respectively.Hydrodynamic simulation was conducted in the platform of commercial software package，ANSYS CFX 10.0，by combining the classical two-fluid model of turbulence and GRACE drag model.The computational distributions of bubble size from the MUSIG（multiple size group）model considering bubbles breakup and coalescence were in good agreement with experimental data，which showed that this model could be used to predict the bubble size distribution in the gas-liquid bubble column.
