“…This phenomenon exists widely in compressors, fans, pumps and turbines. It is a very complicated physical phenomenon, as it not only is a typical fluid–solid two-phase turbulent flow, 1 but also involves many factors that influence the erosion behavior of the material, including the erodent particle velocity and size, the impact angle and the properties of the eroded materials. 2 Erosive wear of turbomachinery can lead to a reduced blade chord, change of the blade shape and increased blade surface roughness.…”

“…For example, the use of filters is not feasible for jet engines. 1 The development of erosion resistant materials will inevitably encounter difficulties; many defects of erosion resistant coating, including porosity, pinholes, cracks, cannot be completely eliminated for the brittle coating on the soft substrate and will degrade the erosion resistance of coatings. 6,7 Therefore, a new method, which is an alternative, inexpensive and important approach to improve anti-erosion performance of turbomachinery blades, is demanding and it is anticipated to be proposed to design turbomachinery blades against erosion in the design stage through its geometry variation.…”

This paper presents an anti-erosion design approach of multidisciplinary design optimization (MDO) for turbomachinery to improve the erosion resistance of the blades, and its application to the design of an industrial mixed flow fan is given. The method is based on a concept for turbomachinery anti-erosion design in the aerodynamic design stage by modifying the geometry of the turbomachinery. The MDO approach replaces the traditional time consuming design method through automatic analyses of the aerodynamic performance, stress distribution and erosion characteristics, controlled by the optimization strategy. In the MDO approach, a multi-objective optimization algorithm non-dominated sorting genetic algorithm-II combined with radial basis function meta-model is used to find the compromise between the conflicting demands of high-efficiency and low average erosion rate with constraints on the pressure ratio and the safety factor for the blade; finite element method is used to analyze the static mechanical responses of the blade; a Navier-Stokes solver is used to predict the aerodynamic performance; solid particle paths in a viscous flow are calculated by Lagrangian method, and then the prediction of erosion is performed based on Tabakoff erosion model. Both the aerodynamic and anti-erosion performances of three selected robust optimal solutions on the Pareto front are compared to those of the baseline. The results show that the main reason for the efficiency improvement of the optimized blades is probably the smaller flow separation region and weaker secondary flows. Further comparative analysis between the baseline blade and the compromise blade for the impinging parameters is presented, and the erosion rate of compromise blade can be considerably decreased due to the lower impact velocity, suitable impact angle and fewer impact times in comparison with that of the baseline blade. As a conclusion, it can be drawn that the proposed approach gives a further opportunity for turbomachinery anti-erosion design in consideration of other disciplines, and the methodology presented can be also applied to other turbomachinery and anti-erosion problem by a minor modification.

“…Also, the sand corrosion behavior for ceramic coating was studied using a computational fluid dynamics model. The numerical results MATS-19-1214, Zhang, Page 4 for the eroded surface geometry and the performance deterioration showed the same tendency as the experimental data [10]. Also, non-ordinary state-based peridynamics was used to understand the fracture in brittle ice due to particle impact.…”

In this work, the impact behavior of an alumina spherical particle on alumina coating is modeled using the smoothed particle hydrodynamics (SPH) method. The effects of impact angle (0°, 30°, and 60°) and velocity (100 m/s, 200 m/s, and 300 m/s) on the morphology changes of the impact pit and impacting particle, and their associated stress and energy are investigated. The results show that the combination of impact angle of 0° and velocity of 300 m/s produces the highest penetration depth and largest stress and deformation in the coating layer, while the combination of 100 m/s & 60° causes the minimum damage to the coating layer. This is because the penetration depth is determined by the vertical velocity component difference between the impacting particle and the coating layer, but irrelevant to the horizontal component. The total energy of the coating layer increases with the time, while the internal energy increases with the time after some peak values, which is due to energy transmission from the spherical particle to the coating layer and the stress shock waves. The energy transmission from impacting particle to coating layer increases with the increasing particle velocity, and decreases with the increasing inclined angle. The simulated impact pit morphology is qualitatively similar to the experimental observation. This work demonstrates that the SPH method is useful to analyze the impact behavior of ceramic coatings.

When a fluid machine operates in particulate environments, particles suspending in the atmosphere cause the fluid machine some problem. This research is to focus on particulate erosion phenomenon whereby solid particles impinging on a wall cause serious mechanical damage to the wall surface. Particulate erosion leads to unwanted degradation of the performance and life of various machines. Particulate erosion of jet engines is important problem for aviation engineer. Extensive particle ingestion by jet engines occurs at takeoff and landing, which is the principal cause of particulate erosion. The authors investigated performance deterioration in single stage compressor due to particulate erosion, and clarified the mechanism. However, particulate erosion phenomenon in multi stage compressor is not well known although compressor of jet engine consists of multiple stages. In the present study, particulate erosion phenomenon in a two-stage compressor is investigated. The results show that inlet particle velocity of second stage is smaller than that of first stage and the particles cluster around the tip.
