Measurement of the axial gas dispersion coefficient in bubble columns of several diameters via gas flow modulation

This dataset was aquired during gas flow modualtion experiments for determining the axial gas dispersion coefficient in bubble columns. The applied measurement technique is gamma-ray densitometry and the dataset consists of densitometry measurements at several axial positions in the bubble columns. Columns of 100, 150 and 330 mm internal diameter were tested. The 100 mm ID column was tested with three different gas spargers to investigate the effect of the gas distributor on gas dispersion. Several operating conditions were tested inside of the homogenous flow regime.

本数据集采集于用于测定鼓泡塔（bubble columns）轴向气体弥散系数的气流调制实验。本次实验采用的测量技术为伽马射线密度计法（gamma-ray densitometry），数据集包含鼓泡塔多个轴向位置处的密度计测量数据。本次实验共测试了内径分别为100 mm、150 mm与330 mm的鼓泡塔；其中内径100 mm的鼓泡塔采用三种不同的气体分布器开展实验，以探究气体分布器对气体弥散过程的影响。实验在均相流工况范围内测试了多种操作条件。
