Lagrangian–Lagrangian modeling for a solid–liquid flow in a cylindrical tank

Three-dimensional simulation of gas–solid–liquid flows using the DEM–VOF method

“…The fluid drag force is relatively dominant while the other hydrodynamic forces are sometimes neglected, see e.g. Di Renzo and Di Maio (2007), Sakai et al (2012). Therefore, we will only accept a drag-related term as the fluid-particle interaction:…”

Discrete element simulation for the evaluation of solid mixing in an industrial blender

“…Very recently, new Lagrangian-Lagrangian approaches have been developed to simulate solid-liquid flows involving free surfaces, where the DEM is coupled with a Lagrangian CFD approach such as the smoothed particle hydrodynamics (SPH) method [22] or the moving-particle semi-implicit (MPS) method [23]. The Lagrangian-Lagrangian approach is thus referred to as the DEM-MPS method [24][25][26]or the DEM-SPH method [27]. These methods can be used to simulate complex solid-fluid coupling problems such as those of wet ball mills.…”

Numerical investigation of erosion and heat transfer characteristics of molten jet impinging onto solid plate with MPS–LES method

“…It has advantages in capturing fluid interface and free surface with large deformation and fragmentation, and the problems of grid distortion and numerical diffusion could be avoided. MPS method has been successfully applied in various research fields involving multi-phase flow [9][10][11][12][13]. In terms of mechanistic study of nuclear severe accident phenomena, it was also applied to fuel-coolant interaction (FCI) [14,15], steam explosion [16], molten corium stratification [17,18], molten corium concrete interaction (MCCI) [19] and core degradation of sodium-cooled fast reactor (SFR) [20].…”
