Hydrodynamics in a bubble column – Part 1: Two-phase flow
Listed in RODARE
Multiphase computational fluid dynamics (CFD) simulation is a useful tool to study the hydrodynamics in a bubble column, if appropriate closure models are known.
Description
Systematic assessment of different models is an ongoing venture that benefits from improved validation data. The present study accumulates a database on two-phase flow experiments in a bubble column.
This is achieved by using a combination of Particle Image Velocimetry and Shadowgraphy to measure the liquid velocity field and gas dispersion properties simultaneously. This methodology is applied for different needle diameters and gas flow rates. A detailed description of the experimental setup can be found in Sommer et al. (2023) .

The experimental data (Table 1) described in this repository is structured into different folders and files as follows: Level 1: Folders classified by measurement configuration: TX_Jg_Y_Di_ZZZ as outlined in Table 1 TX = Identifier Jg_Y = Superficial gas velocity in mm/s Di_ZZZ = Inner diameter of the needle in µm Level 2: Folders classified by measurement height: Z_XXX Z_XXX = Measurement height in mm Level 3: csv files classified by their analysis parameter: Gas_Eg_ub_over_x.csv: Each csv file consists of five columns, namely the x-coordinate (in m), the gas holdup, the uncertainty of the gas holdup, the averaged bubble rising velocity (in m/s) and the corresponding uncertainty (in m/s).
Liquid_v_z_over_x.csv: Each csv file consists of three columns, namely the x-coordinate (in m), the averaged liquid velocity (in m/s) and the corresponding uncertainty (in m/s). Table 1: Overview of the measurement cases in this repository. | ID | Diameter of needle orifice in µm | Superficial gas velocity in mm/s | |----|----------------------------------|----------------------------------| | T1 | 200 | 2 | | T2 | 200 | 4 | | T3 | 200 | 6 | | T4 | 600 | 2 | | T5 | 600 | 4 | | T6 | 600 | 6 |
