Hybrid Lattice-discrete element method for ballast modeling Comp. Part. Mech. (IF 3.3) Pub Date : 2024-03-07
Abstract Railway ballast modeling can be performed by different approaches, through continuous or discrete models, which have their comparative advantages and disadvantages, such as excessive volumes of material for testing and calibration steps. This paper aims to adapt and propose the use of the Hybrid Lattice-Discrete Element Method for modeling railway ballast aggregates. The advantages of using

Computational 3D-modeling and simulations of generalized heat transport enhancement in cross-fluids with multi-nanoscale particles using Galerkin finite element method Comp. Part. Mech. (IF 3.3) Pub Date : 2024-03-02
Abstract Using ionized fluids in a magnetic field has numerous applications in engineering and industry. Therefore, heat transport in ionized fluids with thermal memory effects should be predicted using numerical simulations. To achieve this objective, the generalized heat transport in ionized fluid (following a cross-rheological constitutive relation) is modeled, and the governing system is solved

A simple and novel coupling method for CFD–DEM modeling with uniform kernel-based approximation Comp. Part. Mech. (IF 3.3) Pub Date : 2024-02-28
Abstract The Eulerian–Lagrangian approach is commonly employed in particulate flows, which can be classified into two subcategories: unresolved computational fluid dynamics-discrete element method (CFD–DEM) and resolved CFD–DEM. When the particle sizes are comparable to the cell sizes, the interphase coupling is not straightforward anymore and both the conventional unresolved CFD–DEM and resolved CFD–DEM

Abstract Smoothed molecular dynamics (SMD) method is an efficient mesoscopic method by introducing one set of background mesh and mapping procedure into the molecular dynamics (MD) flowchart. The motion equations are established on the mesh nodes. SMD allows much larger time-step size compared to MD. In this paper, the critical time-step size of SMD is thoroughly analyzed, and the effects of mesh cell
