Accurate Measurement of Particle Velocity using a Double Disc Anemometer in Erosive Wear Experiments - Data

Description

This data repository is supporting the findings within the manuscript 'Accurate Measurement of Particle Velocity using a Double Disc Anemometer in Erosive Wear Experiments.' If any of the resources in this dataset are used in support of future published work, please credit the authors of the primary manuscript publication. This paper presents an improved DDA design, automated post-processing procedures, and result verification. We further investigate disc separation distance and shaft angular velocity, with the discussion highlighting the criterion for reliable measurements. We report an approach and a set of procedures that significantly enhance particle velocity measurement using a DDA accurately and economically. A new scarring analysis method was conducted to identify the intricacies of how the instrument’s geometries affect the velocity calculation. The DDA results were validated using state-of-the-art laser Doppler velocimetry equipment (LDV), with an agreement of -2.8% on average. Please refer to https://doi.org/10.1016/j.triboint.2024.110439
