“…Although Euler-Euler models have also been applied in erosion simulations [122,123], Euler-Lagrange models still remain the workhorse. This is a natural consequence of the fact that erosion models are mostly empirical correlations of the erosion ratio as a function of the local particle velocity, angle of impact and collision frequency.…”

Slurry pipe transport has directed the efforts of researchers for decades, not only for the practical impact of this problem, but also for the challenges in understanding and modelling the complex phenomena involved. The increase in computer power and the diffusion of multipurpose codes based on Computational Fluid Dynamics (CFD) have opened up the opportunity to gather information on slurry pipe flows at the local level, in contrast with the traditional approaches of simplified theoretical modelling which are mainly based on a macroscopic description of the flow. This review paper discusses the potential of CFD for simulating slurry pipe flows. A comprehensive description of the modelling methods will be presented, followed by an overview of significant publications on the topic. However, the main focus will be the assessment of the potential and the challenges of the CFD approach, underlying the essential interplay between CFD simulations and experiments, discussing the main sources of uncertainty of CFD models, and evaluating existing models based on their interpretative or predictive capacity. This work aims at providing a solid ground for students, academics, and professional engineers dealing with slurry pipe transport, but it will also provide a methodological approach that goes beyond the specific application.

“…In recent years, with the rapid development of computer technology and testing techniques, the study of liquid–solid two-phase erosion characteristics has gradually moved from macroscopic to microscopic. For instance, Yu et al 22 constructed a fluid-particle erosion model within the framework of Euler–Euler multiphase flow and extensively investigated the effect of the elastic recovery coefficient on erosion. Based on the combination of experimental studies and numerical simulations, H. Arabnejad et al 23 obtained the effect of particle hardness on erosion patterns.…”

The erosion of the dimple walls is investigated experimentally and numerically. A mathematical simulation framework was proposed to describe quantitatively the morphological evolution of the dimple wall quantitatively. As the wall shape continues to evolve, the wall shear stress, mesh deformation, and erosion rate would decrease and gradually tend to be constant. Two distinct regions have been identified along the dimple's windward wall surface: the wall's central area and the lateral area. In the central region, the wall profile flare occurs mainly in the early stage. In the lateral region, profile flare occurs mainly in the later stages of erosion. The microhardness of the wall surface shows a positive correlation with the erosion rate. The liquid−solid two-phase impinges on the wall at a smaller angle, and the wall material removal process is mainly based on the microcutting and slip mechanism. The results provide theoretical implications for the design of dimple-shaped, wide-channel welded plate heat exchangers.

“…This complicated network of pipelines includes the necessity for usage of numerous and various pipe elbows (bends) and junctions for distribution, transportation, and change of the fluid direction. The pipe elbows are prone to the various damage mechanisms on both internal and external surfaces due to the exposure to fluids and external environments such as corrosion, erosion, erosion-corrosion fatigue, and different other combined damages [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Frequently this leads to the burst in critical parts of piping systems, forced outages, and long term interruptions in operation.…”
