Documentation of the data datacite.description.TechnicalInfo	The time lag between both signals can be derived using cross-correlation between both channels. In combination with the physical distance between the regions observed by each photodiode, the average velocity can be calculated using: v = Δs/Δt with Δs distance between detectors (272 micrometer) and Δt time lag from cross-correlation. A detailed evaluation is presented in the corresponding publication: Kluwe et al. 2025 "Deterministic periodic structures in a model of the human airways" DOI: 10.1007/s00348-025-03971-9

Description of the data datacite.resourceType	The data contains stereo audio (.wav) files where each channel corresponds to the electrical signal produced by a photodiode used for Correlation Velocimetry. The setup is described in detail in the corresponding publication: Kluwe et al. 2025 "Deterministic periodic structures in a model of the human airways" DOI:10.1007/s00348-025-03971-9. The file name convention follows the pattern: f_<breathing frequency in Hz>_<tidal-volume>ml_position_<position-identifier>.wav

Abstract of the dataset dc.description.abstract	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.

Project abstract opara.project.description	A novel measurement technique called "Correlation Velocimetry" (CV) was developed and employed in this project. CV enables point-wise velocity measurements in fluids by measuring the time of flight of tracer particles between two sensors with a known distance apart. The concept and setup are described in detail in the corresponding publication (DOI: 10.1007/s00348-025-03971-9).
