“…In recent years, scholars have also made unremitting efforts and promoted the development of SPH methods in the field of solid mechanics. Furthermore, SPH has been applied to model complicated manufacturing processes, such as shot peening [151], cutting of materials [152], and water jet abrasion [153]. These applications are classified into four sections, including galaxy, geomechanics, impact dynamics and AM.…”

Smoothed particle hydrodynamics (SPH), as one of the earliest meshfree methods, has broad prospects in modeling a wide range of problems in engineering and science, including extremely large deformation problems such as explosion and high velocity impact. This paper aims to provide a comprehensive overview on the recent advances of SPH method in the fields of fluid, solid, and biomechanics. First, the theory of SPH is described, and improved algorithms of SPH with high accuracy are summarized, such as the finite particle method (FPM). Techniques used in SPH method for simulating fluid, solid and biomechanics problems are discussed. The δ -SPH method and Godunov SPH (GSPH) based on the Riemann model are described for handling instability issues in fluid dynamics. Next, the interface contact algorithm for fluid-structure interaction is also discussed. The common algorithms for improving the tensile instability and the framework of total Lagrangian SPH are examined for challenging tasks in solid mechanics. In terms of biomechanics, the governing equations and the coupling forces based on SPH method are exemplified. Then, various typical engineering applications and recent advances are elaborated. The application of fluid mainly depicts the interaction between fluid and rigid body as well as elastomer, while some complicated fluid-structure interaction ocean engineering problems are also presented. In the aspect of solid dynamics, galaxy, geotechnical mechanics, explosion and impact, and additive manufacturing are summarized. Furthermore, the recent advancements of SPH method in biomechanics, such as hemodynamically and gut health, are discussed in general. In addition, to overcome the limitations of computational efficiency and computational scale, the multiscale adaptive resolution, the parallel algorithm and the automated mesh generation are addressed. The development of SPH software in China and abroad is also summarized. Finally, the challenging task of SPH method in the future is summarized. In future research work, the establishment of multi-scale coupled SPH model and deep learning technology in solid and biodynamics will be the focus of expanding the engineering applications of SPH methods.

“…From an applicational point of view, SOPJ combines features of both the pulsed and cavitation jets. High-speed water jets are suitable for mining engineering due to their high erosion capacity, and researchers have conducted experimental [7] and numerical simulation studies [8] on the application of an abrasive water jet to mining. In a submerged environment with the impact of a self-oscillation cavitation water jet, sandstone is prone to large damaged areas [9].…”

High-speed water jets are widely used in deep mining and the in-depth study of jet characteristics helps to improve drilling efficiency. Three-dimensional Large Eddy Simulation is used to simulate turbulent flows generated by an organ-pipe nozzle. The simulation is validated with existing experimental data and is focused on the evolution and interaction of cavitation bubbles and vortices. Dynamic mode decomposition is performed to extract structural information about the different motion modes and their stability. Results show that the dominant fluid frequency is positively correlated with inlet pressure while unrelated to the divergence angle. Meanwhile, jets’ oscillation is amplified by a large divergence angle, which facilitates the occurrence of cavitation. Results about the flow field outside of an organ-pipe nozzle advance the understanding of the basic mechanism of cavitation jets.

The distribution of abrasive particles in fluids is an important research topic in the study of abrasive waterjet cutting processes. However, it is impossible to obtain the accurate distribution law and influencing factors by performing only experiments; therefore, it is necessary to study abrasive waterjet cutting processes with the help of numerical models. The existing numerical models usually adopt the form of artificial settings for the distribution of abrasive particles in fluid. This method cannot accurately simulate the random distribution of particles. In this paper, the random algorithm method is used to simulate the impact azimuth and the random distribution of abrasive particles in water. The smoothed particle hydrodynamics (SPH) method is used to simulate the distribution of abrasive particles and the process of jet impingement. The influence of the particle distribution on the simulation results is studied. Comparisons show that the dent formed by the jet impinging on the target with random abrasive particles is similar to the dent from the actual cut, and the contour distribution of the dent is more uniform than that of the cut. The simulation results obtained by the SPH method are accurate. Keywords: abrasive waterjet cutting; random algorithm; SPH algorithm; cutting profile IntroductionAn abrasive waterjet is a solid-liquid two-phase medium jet formed by mixing abrasive particles and high-speed water. The main difference between the abrasive waterjet and pure waterjet is that the cutting pressure of the abrasive waterjet is less than that of the pure waterjet, but the cutting efficiency is improved, and there is no thermal reaction or chemical reaction during the cutting process. This technology is widely used in the fields of oil exploitation, mechanical processing, mining and tunnel excavation. The influence of abrasive particles is the most critical and complex factor affecting the abrasive waterjet cutting process. Clarifying the distribution and movement of particles in water is of great importance for understanding the cutting process. M. S. eltoby [1] established a finite element analysis model of a micro abrasive erosion material, and the model was solved to simulate the erosion process of multiple particles. However, during modeling, the abrasive geometry was simplified to a spherical shape, and the sharp edges of the abrasive particles were ignored. Babets et al. [2] used the volume of fluid (VOF) model to take the fluid medium as the continuous phase and the abrasive particles as the dispersed phase, and the Lagrangian method was used to track the particles to obtain the variation rules of parameters such as the velocity, turbulent kinetic energy, density and particle trajectory. Ahmed et al. [3] considered both abrasive particles and water to be continuous phases while analyzing them using the Euler method, and determined the optimal incident angle of abrasive particles. Feng [4] used the SPH method to numerically model the abrasive waterjet cutting process. In the model, abrasive par...
