Special Issue Information

Dear Colleagues,

In recent decades, there have been rapid advances in particle methods. These methods have different numerical schemes from grid-based numerical methods and have attracted researchers from all over the world for various applications, the most representative of which is the Smoothed Particle Hydrodynamics (SPH) method. SPH is a purely Lagrangian mesh-free numerical method that has unique advantages in dealing with complex flow problems containing free surfaces or multi-phase interfaces. With the continuous improvement of computational accuracy and stability, the SPH method has been widely used in many fields of science and engineering.

This Special Issue, entitled "Advances in Smoothed Particle Hydrodynamics (SPH) Method for Complex Flows," aims to cover recent advances in the development and application of SPH for complex flows. It will review the latest progress of the SPH basic theory, focusing on its research progress in interface flows, fluid–solid coupling, non-Newtonian fluids, and other fields, as well as future developments. Topics will include, but are not limited to, methods and/or applications in the following areas:

  • The application of the SPH method to complex fluid flow problems in chemical engineering;
  • Recent advances in SPH and other advanced mesh-free methods;
  • Coupling of the SPH method with PD, DEM, MPM, and other methods to solve complex flow problems;
  • Applications of SPH for the simulation of soft materials, fluid–structure interaction, geomechanics, fluid–particle interaction, multi-phase interactions, additive manufacturing, nano-, non-Newtonian, and visco-elastic fluids, etc.

The problems of large deformations, failures, and fractures that agricultural tillage tools may encounter during the cultivation process has long been a concern in the field of agricultural machinery design and manufacturing. It is important to establish a more accurate numerical model to effectively predict tools’ plastic deformation failures and ductile fracture failures. This research develops a numerical model for predicting the plastic deformation failure and ductile fracture failure of agricultural tillage tools using the smoothed particle hydrodynamics (SPH) method and the Johnson–Cook constitutive model. The model uses the Drucker–Prager criterion to describe the elastic–plastic constitutive behavior of the soil, the von Mises criterion to describe the Johnson–Cook constitutive model of the tool, and the coupling condition with the Lennard-Jones repulsive force to describe the interaction between the tool and soil. The numerical results show that the proposed model can effectively simulate the interaction between the tool and soil, as well as the tool’s plastic deformation failure and ductile fracture failure during the agricultural cultivation process. It can also predict the variation trend of the cutting force of the tool. This helps to provide a new approach for the numerical simulation of such problems. Full article
