# Raw Data Archives ## Dataset reference This README documents the split raw-data archives of the dataset: **Dataset title:** PhD Results Repository **Dataset DOI:** https://doi.org/10.15480/882.16414 **Creator:** Ryan Rautenbach **Affiliation:** Institute of Multiphase Flows, Hamburg University of Technology (TUHH), Hamburg, Germany **ORCID iD:** 0000-0002-6943-2077 **Version:** 1.0 **Date:** 09.06.2026 **License:** CC BY 4.0 for raw data, processed data, results, figures, and supplementary material; MIT License for code and scripts For the full dataset-level documentation, recommended citation, related publication, software environment, and reuse information, see the main `README.md`. ## Purpose of this README This file documents the raw numerical simulation archives contained in the repository. The original raw-data folder was split into several ZIP archives for storage and upload to TORE. Therefore, the raw data are not provided as one single `00_RAW_data/` directory. Instead, the individual archives listed below together represent the raw numerical simulation data used as the basis for later post-processing, analysis, and figure generation. The split into several archives is organisational and storage-related. It does not indicate separate studies. ## Raw data archives ### `00_RAW_data-03_cell_lifeline.zip` Raw cell-lifeline data used for particle-tracking, axial probability-of-presence analysis, axial residence-time analysis, and related numerical reactor characterisation. ### `00_RAW_data-work_on_multiphase_FTLE-FTLE_simulations-0.00vvm.zip` Raw FTLE simulation data for the non-aerated operating case. ### `00_RAW_data-work_on_multiphase_FTLE-FTLE_simulations-0.05vvm.zip` Raw FTLE simulation data for the aerated operating case at 0.05 vvm. ### `00_RAW_data-work_on_multiphase_FTLE-FTLE_simulations-0.10vvm.zip` Raw FTLE simulation data for the aerated operating case at 0.10 vvm. ### `00_RAW_data-work_on_multiphase_FTLE-FTLE_simulations-0.15vvm.zip` Raw FTLE simulation data for the aerated operating case at 0.15 vvm. ### `00_raw_simulations_no_vol_results.zip` Raw simulation results excluding large volumetric result files. This archive contains retained numerical simulation outputs without the full volume-result datasets in order to reduce storage size. ## Typical contents of the raw archives The raw data archives contain numerical simulation cases and directly exported solver outputs. Depending on the archive, this may include: * numerical simulation case setups * geometry files * `input.xml` files * solver logs * output folders * probe statistics * scalar fields * particle data * FTLE-related simulation data * archived or copied result sets Many simulation folders contain repeated solver-output structures such as: * `Input` * `Output` * `Stats` * `BoundaryConditions` * `ParticleFreq...` * `Slice...` * `Volume...` * probe-specific folders These repeated structures are documented at archive or directory level rather than by listing every timestep, probe file, slice file, volume file, or repeated solver-output file individually. ## File formats and data structures Depending on the archive, the raw data may include the following file formats: * `.zip` compressed archives * `.xml` simulation input files * `.txt` tabular or solver-output files * `.csv` exported or processed tabular files, where included * `.vti` volumetric simulation output files, where retained * image or figure files such as `.png`, `.svg`, or `.pdf`, where included * Python scripts or notebooks, where included as part of the raw or semi-raw processing context The exact file structure differs between simulation cases. Repeated solver-output directories are therefore described by archive and directory type rather than by listing every individual output file. ## Relation to processed data Derived analysis files, post-processing scripts, extracted results, plots, and comparison datasets are stored separately in: `01_processed_data_related_RAW_data.zip` Raw solver files should generally not be edited directly. Any corrections, derived datasets, or analysis outputs should be documented and stored in the processed-data archive instead. ## Software and system environment The raw simulation data were generated using M-Star CFD / M-Star LBM-LES and analysed using Python-based post-processing tools. For the consolidated software and system-environment information, including software versions and general hardware requirements, see the main `README.md`. Reprocessing the full raw simulation data may require substantial local storage and high-performance computing resources. Some archives may require several hundred GB of free local storage after extraction. ## License and reuse The raw data archives are licensed under the **Creative Commons Attribution 4.0 International License (CC BY 4.0)**, unless stated otherwise. Code and scripts contained elsewhere in the repository are licensed under the **MIT License**, unless stated otherwise. Users reusing the raw data should cite the dataset DOI: https://doi.org/10.15480/882.16414 For the recommended citation and related dissertation citation, see the main `README.md`. ## Handling notes The ZIP archives are large and should be extracted only when needed. Raw solver files should not be manually edited unless a correction is explicitly documented. Derived analysis should be performed using the processed-data archive and associated scripts where available. The individual raw-data archives together form the raw-data basis for the dissertation-related analyses.
