Experimental Methods in Chemical Engineering: Discrete Element Method—DEM
The Canadian Journal of Chemical Engineering, 2019The discrete element method (DEM) is a time‐driven simulation technique based on a Lagrangian description of particle motion that predicts the flow of granular matter and fine powders in conveying, mixing, drying, and heterogeneous gas‐(liquid)‐solids reactors.

Evaluation of an FPGA Implementation of the Discrete Element Method
2001The Distinct Element Method (DEM) is a numerical method for the simulation of the behaviour of media consisting of discrete particles, and is widely used for process optimisation in the food and pharmaceutical industries. The DEM is very computationally expensive, but has properties that make it amenable to acceleration by reconfigurable computing ...

Some Recent Applications of the Discrete Element Method
Civil-Comp Proceedings, 1991Abstract The discrete element method is a powerful numerical technique for the stress analysis of certain classes of structure. It does not possess the generality of the finite element method but neither does it require massive computing power. It seems applicable to line structures where Saint Venant's principle is relevant and it produces second ...

Discrete Element Method for Slope Stability Analysis
Journal of Geotechnical Engineering, 1992Limit equilibrium methods for slope stability analysis do not, in general, satisfy the overall equilibrium conditions; they must make assumptions regarding the inclination and location of the interslice forces. An alternative slope analysis based on the discrete element method is presented to avoid these drawbacks.

An erosion model for the discrete element method
Particuology, 2017Abstract A shear impact energy model (SIEM) of erosion suitable for both dilute and dense particle flows is proposed based on the shear impact energy of particles in discrete element method (DEM) simulations. A number of DEM simulations are performed to determine the relationship between the shear impact energy predicted by the DEM model and the ...

DISCRETE ELEMENT METHOD FOR MULTISCALE MODELING
Journal of Multiscale Modelling, 2010A discrete element method (DEM) has been developed to provide highly accurate and detailed predictions of the Lagrangian particle phase. Especially in this study, DEM has been used together with an Eulerian approach for the fluid phase to look at interphase exchange phenomena in a multiphase-multiscale modeling approach.

A discrete version of the boundary element method
Engineering Analysis, 1984Abstract It is well known that several problems described by partial differential equations can be rewritten in terms of integral equations. For time independent problems, Fredholm integral equations are obtained, whereas time dependent problems give rise to Volterra integral equations.
