“…In addition, these model do not account for the stream density, particle-particle collision and the energy loss in particlesurface collision. To account for these factors, a modified model for particle-particle interaction was proposed [6]. The modified model predicted the existence of a critical flux below which the interparticle interaction is unlikely to occur, in agreement with experimental observation.…”

“…In order to capture the real physical phenomena of the airflow, e.g., the convection terms, diffusion term, turbulent viscosity, velocity, and pressure, with a reasonable accuracy, the Quadratic Upstream Interpolation Central Kernel (QUICK) scheme [18] is used to discretize Eqs. (1)(2)(3)(4)(5)(6), incorporating with hybrid polyhedral meshes in Eulerian space. The QUICK scheme is developed based on a weighted average of second-order-upwind and central interpolations of the variables to form the 3rd order of accuracy scheme [18].…”

“…In particular, in this study, the effect of particle-particle interaction on both erosion rate and erosion pattern was compared with that without including the particle-particle interaction and also experimental results. Both airflow behavior and particle behavior at the interaction region were studied in depth Regarding the effects of particle-particle interaction on material erosion, several interesting works have been performed using analytical analysis [4][5][6], numerical modeling [7][8][9][10] as well as experimental measurements [11,12]. For analytical analysis, Andrews and Horsfield [4] developed a theoretical model for particle-particle interaction to study the effects of particle flux on the erosion process.…”

“…Only a portion of particles actually impacts on the target surface while the others lose their way to target surface owing to the interaction between the incoming and rebounding particles. These findings are studied in detail by many researchers [28][29][30]. For pot-and centrifugal-type impingement experimental rigs, the correlation between erosion rates and sand concentration is highly nonlinear in nature.…”

High-entropy alloys (HEAs) have gained extensive attention due to their excellent properties and the related scientific value in the last decade. In this work, Al x CoCrFeNiTi 0.5 HEA coatings (x: molar ratio, x = 1.0, 1.5, 2.0, and 2.5) were fabricated on Q345 steel substrate by laser-cladding process to develop a practical protection technology for fluid machines. The effect of Al content on their phase evolution, microstructure, and slurry erosion performance of the HEA coatings was studied. The Al x CoCrFeNiTi 0.5 HEA coatings are composed of simple face-centered cubic (FCC), body-centered cubic (BCC) and their mixture phase. Slurry erosion tests were conducted on the HEA coatings with a constant velocity of 10.08 m/s and 16-40 meshs and particles at impingement angles of 15, 30, 45, 60 and 90 degrees. The effect of three parameters, namely impingement angle, sand concentration and erosion time, on the slurry erosion behavior of Al x CoCrFeNiTi 0.5 HEA coatings was investigated. Experimental results show AlCoCrFeNiTi 0.5 HEA coating follows a ductile erosion mode and a mixed mode (neither ductile nor brittle) for Al 1.5 CoCrFeNiTi 0.5 HEA coating, while Al 2.0 CoCrFeNiTi 0.5 and Al 2.5 CoCrFeNiTi 0.5 HEA coatings mainly exhibit brittle erosion mode. AlCoCrFeNiTi 0.5 HEA coating has good erosion resistance at all investigated impingement angles due to its high hardness, good plasticity, and low stacking fault energy (SFE).

Numerical and experimental investigation of the erosion of zirconia particulate‐reinforced epoxy matrix composites by angular silicon carbide particles

et al. 2020

An smooth particle hydrodynamics/finite element (SPH/FEM) model was developed to simulate the erosion of zirconia particle‐reinforced epoxy composites, due to the overlapping impacts of angular particles at both perpendicular and oblique incidences. For each composite target, multiple sub‐volumes, each having their own random reinforcement distribution, were modeled. The reinforcements were assumed as noneroding and nondeforming and were distributed in the modeled sub‐volumes according to the random distributions measured in the actual samples. Erosion tests were performed to verify the numerical model, and it was found that the erosion rates of the zirconia‐reinforced composites were in all cases significantly lower than the neat epoxy. The experimentally‐observed erosion mechanisms were successfully simulated by the model, and the predicted erosion rates matched the measured ones to within 2% to 11%. It is anticipated that similar models can be used to predict erosion of other particulate composite systems whose reinforcement erosion and fracture is negligible compared to the matrix erosion.
