The discrete element method (DEM) and the moving particle semi-implicit (MPS) method are
the most popular mesh-free particle methods in the discontinuum and continuum. This paper …

Tons of products are facilitated through powder mixing processes. The quality of the final
products is highly influenced by the mixing state. Hence, detailed information about the …

A ribbon mixer is often employed in powder mixing in a wide range of engineering fields.
The structure of the ribbon mixer is extremely complicated. This structure makes it difficult to …

We describe the effectiveness of the coarse-grain model of the discrete element method
(DEM) in solid mixing in a spouted bed. The coarse-grain model was developed originally to …

The so-called coarse-grained discrete element method (DEM) is used here for efficient
simulations of large-scale particle systems as its effectiveness has been successfully verified …

Large-scale gas-solid flow systems, eg, fluidized beds, cyclone separators and pneumatic
conveyors, are often encountered in chemical engineering. Numerical modeling …

The discrete elements method (DEM) coupled with computational fluid dynamics (CFD) is
widely employed in the numerical simulation of a multiphase flow including solid particles …

Multiphase flows with solid particles are commonly encountered in various industries. The
CFD–DEM method is extensively used to simulate their dynamical behavior. However, the …

Gas–solid–liquid three-phase flow systems are ubiquitous in chemical and energy
