CFD-DEM
Encyclopedia
CFD-DEM model is suitable for the modelling or simulation of fluid
-solids or fluid-particles systems. In the CFD-DEM, the motion of discrete solids or particles phase is obtained by the Discrete Element Method (DEM) which applies Newton's laws of motion to every particle, while the flow of continuum fluid is described by the local averaged Navier–Stokes equations that can be solved using the traditional Computational Fluid Dynamics (CFD) approach. The interactions between the fluid phase and solids phase is modeled by use of Newton's third law.
The direct incorporation of CFD into DPM to study the gas fluidization process so far has been
attempted by Tsuji et al. and most recently by Hoomans et al..
Fluid
In physics, a fluid is a substance that continually deforms under an applied shear stress. Fluids are a subset of the phases of matter and include liquids, gases, plasmas and, to some extent, plastic solids....
