Analysis of micro and nano particle erosion by analytical, numerical and experimental methods: A review

Erosion is one of the vital factors to consider for damage of solid-liquid, solid-gas multiphase flow system. The presence of solid particles in the fluid domain initiates the erosion. This paper focuses on the erosion analysis methods. Different erosion models for analytical and numerical investigation are discussed along with experimental test processes for erosion. Further, possible techniques used for analyzing the eroded surfaces are discussed. This study will be helpful for researchers working on erosion phenomena which can find erosion by analytical, numerical as well as experimental ways. Erosion prediction before implementation will save the system performance degradation. Lastly, consideration of the factors like temperature, impact angle variation during the flow and complex geometry is recommended for future study.
