“…These studies highlight the method's role in improving energy efficiency and understanding environmental impacts. Chen et al and Cui et al focused on particle erosion under multiphase bubble flow conditions, which is critical for designing durable equipment and minimizing maintenance costs in industrial processes [97,98]. The erosion mechanism under multiphase bubble flow conditions is primarily due to the impact deformation and micro-cutting effects of solid particles on the pipe wall.…”

Complex fluid–solid systems generally exist in process engineering. The cognition of complex flow systems depends on numerical and experimental methods. The computational fluid dynamics–discrete phase method simulation based on coarsening technology has potential application prospects in industrial-scale equipment. This review outlines the computational fluid dynamics–discrete phase method and its application in several typical types of process engineering. In the process research, more attention is paid to the dense condition and multiphase flow. Furthermore, the CFD-DPM and its extension method for comprehensive hydrodynamics modeling are introduced. Subsequently, the current challenges and future trends of the computational fluid dynamics–discrete phase method are proposed.

“…The effect of the number of cells on the simulation results was indicated by the relative error. The definition of relative error has been given in previous study [22]. When the relative error is less than 5%, the number of cells can be considered to have satisfied the requirement of grid independence.…”

The black-water regulating valve is very easy to be damaged due to the erosion of the key components, such as valve spool and valve seat. This work presents the failure analysis of the spool and seat of regulating valve in the black-water treatment system. Scanning electron microscopy (SEM) and X-ray energy dispersive spectrometer (EDS) were used to detect the morphology and chemical compositions of failure valve samples. The computational fluid dynamics (CFD) method was also adopted to simulate the medium flow characteristics in black-water regulating valve. The results show that most erosion areas of the valve occur at the spool-seat throttle zone. The erosion profile is mainly manifested in plastic deformation pits, cutting abrasions, furrows, pinhole pits and impact pits. The particles and cavitation bubbles move toward the throttle zone driven by black-water medium, causing particles impact and bubbles collapse. The valve suffered severe particle erosion and cavitation erosion under the particle impact and bubble collapse, finally resulting in its failure.

“…Moreover, most erosion models are established based on the experimental data obtained in rather simple flows, which raises concerns about their Processes 2024, 12, 1150 2 of 47 applicability to relatively complex flow fields. For instance, when solid particles are carried by a flowing liquid, the generation of bubbles due to phase change or external gas injection will alter particle trajectories [3]. Moreover, in gas-dominated multiphase flow, liquid can form a film over the solid surface, and the liquid film assumes the function of buffering the impact of particles on the surface.…”

The erosive wear encountered in some industrial processes results in economic loss and even disastrous consequences. Hitherto, the mechanism of the erosive wear is not clear, especially when the erosive wear is caused by large particles (>3.0 mm) carried by a flowing liquid. Current approaches of predicting erosive wear need improvement, and the optimization of relevant equipment and systems lacks a sound guidance. It is of significance to further explore such a subject based on the relevant literature. The present review commences with a theoretical analysis of the dynamics of large particles and the fundamental mechanism of erosion. Then the characteristics of the erosion of various equipment are explicated. Effects of influential factors such as particle size and properties of the target material are analyzed. Subsequently, commonly used erosion models, measurement techniques, and numerical methods are described and discussed. Based on established knowledge and the studies reported, some expectations for future work are proposed.
