    Data and code for A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors
    (2026-06-26)
    Rautenbach, Ryan
    This dataset contains the raw and processed experimental data, along with the analysis code, for the publication titled “A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors.” The data were obtained from optical measurements based on the reversible redox reaction of methylene blue in gas–liquid stirred tank bioreactors. They include time-resolved colourisation data used to derive spatial information on oxygen supply heterogeneities under varying hydrodynamic conditions (e.g. different impeller speeds). The dataset is structured into raw measurement files, processed results, and scripts for data evaluation and visualisation, enabling reproducibility and further analysis. (2026-04)

    This dataset contains experimental and numerical results supporting a 30 L stirred-tank mixing-time study conducted at the Institute of Multiphase Flows, Hamburg University of Technology (TUHH). It includes raw and processed measurements from laboratory mixing experiments, M-Star LBM-LES simulations, and complementary Fluent CFD runs. The data are organized into subdirectories covering experimental probe time series, simulation outputs, post-processing scripts, and final compiled tables and figures used in the associated publication. Together, they enable the reproduction of key analyses on macro-scale flow dynamics, mixing-time evaluation, and grid-resolution sensitivity. All files are documented with folder-level README files explaining their structure, naming conventions, and relevance to the published results.
