CFD-DEM model : ウィキペディア英語版
CFD-DEM model

A CFD-DEM model is suitable for the modeling or simulation of fluid-solids or fluid-particles systems. In a typical CFD-DEM model, the phase motion of discrete solids or particles is obtained by the Discrete Element Method (DEM) which applies Newton's laws of motion to every particle〔Cundall P. A., Strack O. D. L., (1979). Discrete numerical-model for granular assemblies. Geotechnique, 29, 47-65〕 and the flow of continuum fluid is described by the local averaged Navier–Stokes equations that can be solved by the traditional Computational Fluid Dynamics (CFD).〔''e.g.'', see 〕 The model is first proposed by Tsuji et al.〔Tsuji Y., Tanaka T., Ishida T., (1992). Lagrangian numerical-simulation of plug flow of cohesionless particles in a horizontal pipe. Powder Technology, 71, 239-250〕〔Tsuji Y, Kawaguchi T, Tanaka T. Discrete Particle Simulation Of 2-Dimensional Fluidized-Bed. Powder Technology. 1993 Oct;77(1):79-87〕 The interactions between the fluid phase and solids phase is better modeled according to Newton's third law.
