Item type:Research Data, Access status: with files , Data supplement for publication: Lagrangian µ-Particle Tracking Velocimetry Analysis of Microscale Flow over Structured Surfaces(2026-09-17); ; ; The TUHH Open Research (TORE) repository contains the raw and processed data underlying the publication "Lagrangian µ-Particle Tracking Velocimetry Analysis of Microscale Flow over Structured Surfaces". The dataset includes experimental particle tracking velocimetry (PTV) data, the design files of the investigated structured surfaces, and the corresponding MATLAB analysis scripts. The study investigates flow over micro- and nanostructured surfaces as a basis for improving (bio)reactor design, with a focus on mass transport near the surface. µ-PTV was used to obtain three-dimensional, time-resolved particle trajectories and velocity fields in a microreactor. The Lagrangian analysis shows that rectangular microgrooves increase particle contact with the wall. In particular, when the microgrooves are oriented perpendicular to the flow. The analysis reveals near-surface phenomena such as particle trapping and localized recirculation that are not captured by averaged Eulerian velocities alone. The dataset is accompanied by a detailed REadMe file and a separate folder structure file, which describe the file organization, the naming conventions used throughout the repository, and how the individual files relate to the results reported in the associated publication.Data Type: Experimental Data62 79 - Some of the metrics are blocked by yourconsent settings
Item type:Research Data, Access status: with files , Data for "Millimeter-Scale Lagrangian Sensor Spheres for Local State Monitoring in SMART Reactors: Towards Energy-Autonomous Operation"This dataset contains the underlying measurement data and Python-based analysis scripts supporting the publication “Millimeter-Scale Lagrangian Sensor Spheres for Local State Monitoring in SMART Reactors: Towards Energy-Autonomous Operation”. It includes raw and intermediate data for selected quantitative evaluations, such as power consumption, transmission behavior, energy harvesting, and trajectory-related analysis. The dataset is intended to support traceability and practical reuse of the reported evaluation workflows. Manuscript text and final publication graphics are not the primary subject of this dataset release and should be consulted in the associated journal publication.Data Type: Software ; Data Type: Technical Documentation ; Data Type: Experimental Data61 56 - Some of the metrics are blocked by yourconsent settings
Item type:Research Data, Access status: with files , Optical Profilometer Dataset for Diced Surfaces Obtained with Wafer Dicing Machine at Varying Feed Velocities(2026-01-29); ; Fused silica wafers (1mm thickness) were diced with a wafer dicing machine (Disco DAD3350) at different feed velocities to analyze the impact on the surface roughness. The surface roughness was measured with an optical profilometer (Keyence VK-X3000) in white light interferometer mode. Raw data from the interferometer measurements and a README file are included in this dataset.Data Type: Measurement and Test Data32 43
