Experimental gas phase hydrodynamic data of lab scale bubble column

For the investigation of bubble column hydrodynamics an experimental study using ultrafast electron beam X-ray tomography (UFXCT) has been carried out. Local hydrodynamic parameters were measured in a DN100 bubble column using two types of capillary gas sparger, which are named as 'Type A' and 'Type B' . Nitrogen is used as gas phase and deionized water as liquid phase. For Type B sparger additionally, experiments with sodium hydroxide of different concentrations are given. Experiments were carried out at two different measurement heights, which are located at 10 (L/D = 1) and 70 cm (L/D = 7) above the gas sparger

为研究鼓泡塔流体力学特性，本研究采用超快电子束X射线断层扫描（ultrafast electron beam X-ray tomography, UFXCT）技术开展了实验研究。本研究在DN100规格鼓泡塔内，采用两种分别命名为A型与B型的毛细管式气体分布器，对局部流体力学参数进行了测量。实验以氮气作为气相、去离子水作为液相；针对B型气体分布器，本研究还开展了使用不同浓度氢氧化钠溶液作为液相的实验。实验分别在气体分布器上方10cm（L/D=1）与70cm（L/D=7）两个不同测量高度处进行。

附带的readme.txt文件包含所有必要信息，是解读本实验数据的必备文件。
