Accurate Measurement of Particle Velocity using a Double Disc Anemometer in Erosive Wear Experiments
Accurately characterizing particle velocity ejected from a nozzle in erosive wear experiments is crucial for quantifying erosive wear. Methods like particle imaging velocimetry, laser Doppler velocimetry (LDV) provide precise measurements, but they can be costly. An alternative approach to the above-mentioned methods, at a fraction of the cost, is a velocity measurement with a double disc anemometer (DDA). This paper presents a highly improved DDA design with automated postprocessing procedures and result verification. We report an approach and a set of guidelines 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 LDV equipment, with an agreement of ±2.8% on average.

Accurate measurement of particle velocity using a double disc anemometer in erosive wear experimentsAccurately characterizing abrasive particle velocity ejected from a nozzle in a pressurized airflow is crucial for solid particle erosion quantification, abrasive jet micromachining, and abrasive slurry micro-jet experiments. A double-disc anemometer (DDA) is an economical particle velocity measurement apparatus which is cost effective to implement. The DDA method determines particle velocity using the time it takes for particles to travel a known distance between two rotating discs mounted on the same shaft. Since 1975, the DDA has been used to measure solid particle velocities in gas-particulate flow streams. Particle velocity measurement using a DDA is an intricate process, which the experimental procedure lacks published standardization outlining, operation procedures, comprehensive error analysis, and post-processing advice, all required to report accurate and reliable results. This paper presents a new and improved DDA design, automated post-processing procedures, and experimental validation characterizing the flow development of 66 micron glass bead abrasive blasted with a maximum mean particle velocity of 95.3 m/s. State-of-the-art laser Doppler velocimetry equipment (LDV) was used to validate the DDA results with an agreement of −2.8 % on average. Further, this paper investigates the disc separation distance and shaft angular velocity, discussing configuration recommendations for reliable measurements, with an optimal reported uncertainty of ± 3.2 %. Finally, a novel scarring analysis method was conducted to identify the intricacies of how the instrument’s geometries affect the velocity calculation.more » « less

null (Ed.)Particle pair statistics of inertial particles having average Stokes numbers of 2.1 and 14 are measured in isotropic turbulence at a Reynolds number of Reλ = 240. The radial distribution function (RDF) and mean relative approach velocity are obtained at small separation distances using 2-frame stereoscopic particle tracking velocimetry (stereo-PTV). At small separation distance, the RDF varies by an order of magnitude in the range of Stokes numbers investigated. However, the mean relative approach velocity is found to have a weak dependence on Stokes number. The results are shown to have high accuracy when compared to analogous mono-PTV datasets, and can be used to provide a more reliable estimate of the inter-particle collision rate. The main limitation of the measurement is observed at separation distances less than the laser sheet thickness, where the technique tended to underestimate the mean relative approach velocity.more » « less

Optical flow velocimetry (OFV) is a method for determining dense and accurate velocity fields from a pair of particle images by solving the classical optical flow problem. However, this is an ill-posed inverse problem, which generally entails minimizing a weighted sum of two terms–fidelity and regularization–and the weights in the sum are parameters that require manual tuning based on the properties of both the flow and the particle images. This manual tuning has historically been a consistent challenge that has limited the general applicability of OFV for experimental data, as the calculated velocity field is sensitive to the value of the weights. This work proposes a hierarchical model for the weighting parameters in the framework of a maximum a posteriori-based Bayesian optimization approach. The method replaces the classical Lagrange multiplier weighting parameter with a new, less-sensitive parameter that can be automatically predetermined from experimental images. The resulting method is tested on three different synthetic particle image velocimetry (PIV) datasets and on experimental particle images. The method is found to be capable of self-adjusting the local weights of the optimization process in real-time while simultaneously determining the velocity field, leading to an optimally regularized estimate of the velocity field without requiring any dataset-specific manual tuning of the parameters. The presented approach is the first truly general, parameter-free optical flow method for particle image velocimetry (PIV) images. The developed method is freely available as a part of the PIVlab package.more » « less

Abstract. Despite a rich history of studies investigating fluid dynamics over bedforms and dunes in rivers, the spatiotemporal patterns of sub-bedform bedload transport remain poorly understood. Previous experiments assessing the effects of flow separation on downstream fluid turbulent structures and bedload transport suggest that localized, intermittent, high-magnitude transport events (i.e., permeable splat events) play an important role in both downstream and cross-stream bedload transport near flow reattachment. Here, we report results from flume experiments that assess the combined effects of flow separation–reattachment and flow re-acceleration over fixed two-dimensional bedforms (1.7 cm high; 30 cm long). A high-speed camera observed bedload transport along the entirety of the bedform at 250 frames per second. Grain trajectories, grain velocities, and grain transport directions were acquired from bedload images using semiautomated particle-tracking techniques. Downstream and vertical fluid velocities were measured 3 mm above the bed using laser Doppler velocimetry (LDV) at 15 distances along the bedform profile. Mean downstream fluid velocity increases nonlinearly with increasing distance along the bedform. However, observed bedload transport increases linearly with increasing distance along the bedform, except at the crest of the bedform, where both mean downstream fluid velocity and bedload transport decrease substantially. Bedload transport time series and manual particle-tracking data show a zone of high-magnitude, cross-stream transport near flow reattachment, suggesting that permeable splat events play an essential role in the region downstream of flow reattachment.more » « less
