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

This data repository is supporting the findings within the manuscript 'Accurate Measurement of Particle Velocity using a Double Disc Anemometer in Erosive Wear Experiments.'

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.
