    Correlation Velocimetry inside a model of the human airways
    (Technische Universität Bergakademie Freiberg, 2025-02-07) Bauer, Katrin; Kluwe, Moritz Niklas
    The dataset corresponds to the publication "Deterministic periodic structures in a model of the human airways" by Kluwe et al. 2025. It contains raw data obtained from an optical setup used for point-wise velocity measurements using Correlation Velocimetry in a model of human airways. The recorded data consists of stereo audio files sampling the photo-electric response of two photodiodes to the passage of tracer particles. The time lag between both signals corresponds to the mean time of flight of ensembles of particles between both detectors. Using the known distance between the detectors (272 micrometers), the mean velocity of the tracer particles can be calculated. This dataset includes the raw data evaluated and discussed in the publication.

    Dataset for "CFD Analysis of Mucus Bridge Instability and Breakup in the Vocal Folds"
    (Technische Universität Bergakademie Freiberg, 2025-08-22) Heinrich, Martin
    This data archive accompanies the research paper "CFD Analysis of Mucus Bridge Instability and Breakup in the Vocal Folds" by Heinrich et al. The archive contains OpenFOAM case setups, simulation scripts, and extracted visualization data for the multiphase Volume-of-Fluid CFD simulation of mucus bridge breakup during vocal fold phonation.

    Particle image velocimetry inside in-axis and off-axis stretched Newtonian liquid bridges
    (Technische Universität Bergakademie Freiberg, 2025-05-06) Fritzsche, Lisa; Bauer, Katrin
    Supplemental material for the publication: "Particle image velocimetry of the flow field inside in-axis and off-axis stretched liquid bridges" by Fritzsche, L., Bauer, K., & Schwarze, R. (2025). The study introduces a novel experimental technique that enables comprehensive visualization and measurement of the internal flow field of liquid bridges throughout the stretching process. By embedding the liquid bridge in a refractive-index-matched immiscible outer liquid phase, unobstructed optical access to the entire volume is provided and optical distortions are eliminated. The data collection archived here contains the time-resolved PIV data (velocity fields) for all cases discussed in the publication, raw images for two representative cases (plate speeds 5 mm/s), and evaluated minimum diameters over time (including raw images) for liquid-air systems to compare to the liquid-liquid system of the PIV measurements.

    Research data for: “Forces during film drainage and detachment of NMC and spherical graphite in particle-bubble interactions quantified by CP-AFM and modeling to understand the salt flotation of battery black mass”
    (Technische Universität Bergakademie Freiberg, 2024-12-09) Nicklas, Jan
    This dataset characterizes the particle-bubble interaction for single battery black mass particles (NMC 622 and spherical graphite) in sodium chloride solutions (0.001 mol/L to 0.750 mol/L) for pH 3 to pH 10. The interaction of black mass particles with gas bubbles in the AFM-geometry gives information about the likeliness of particle-bubble-attachment and detachment in salt flotation. The research data consists of two parts: A) the Experimental Atomic Force Microscopy data for the interaction of black mass particles (NMC 622 (NMC) and spherical graphite (SG)) with sessile gas bubbles in salt solutions and B) the Data for the key figures of “Forces during film drainage and detachment of NMC and spherical graphite in particle-bubble interactions quantified by CP-AFM and modeling to understand the salt flotation of battery black mass”.

    Robust Laser Cross Detection
    (Technische Universität Bergakademie Freiberg, 2024-12-12) Kluwe, Moritz Niklas; Hardege, Robert
    The source code repository contains the complete Python implementation of the laser cross detection algorithm, including example datasets. The repository includes synthetic image generation tools, evaluation scripts, and reference implementations of RANSAC and Probabilistic-Hough-Transform methods for comparison. Example datasets feature both synthetic and real-world calibration images, with documentation detailing their usage. All code is thoroughly commented and includes usage examples. The implementation requires common Python libraries (numpy, scipy, lmfit) and provides a straightforward API for integration into existing calibration workflows.
