Abstract: Particle-based simulation methods, such as the discrete-element method and smoothed particle hydrodynamics, have specific advantages in modelling complex three-dimensional (3D) environmental fluid and particulate flows. The theory of both these methods and their relative advantages compared with traditional methods will be discussed. Examples of 3D flows on realistic topography illustrate the environmental application of these methods. These include the flooding of a river valley as a result of a dam collapse,… Show more

“…A promising, though computationally highly expensive, DNS method to tackle granular flows is the DEM (often referred to as well as Distinct Element Method), introduced by Cundall and Strack in 1979 [16]. Recent contributions to the literature using the DEM include Wu and Cocks [17] who investigated the flow of powder into a confined space, Cleary and Prakash [18] who provided impressive results of DEM simulations coupled with Particle Smooth Hydrodynamics (SPH) in the area of environmental sciences (flooding of a river valley as a result of a dam break, landslides, etc.) and Tsuji et al [19] who surveyed a three-dimensional bubbling gas-fluidized bed by parallel DEM-CFD coupling simulation with up to 4.5million particles.…”

“…The role of particle interactions on the flow dynamics constitute typical insights that could be gained into such particle-based modeling methods [7]. Discrete-element methods (DEM), first introduced by Cundall [11] and Cundall and Strack [12], are particularly well suited to model flows of particulate solids [6][7][8][9]18,29,45,50] which is the purpose of this paper. The principal interest of such a method is to represent granular media as an assembly of contacting particles, termed as discrete elements (DE).…”
