Particulate Modeling of Sand Production Using Coupled DEM-LBM

Coupled DEM-LBM method for the free-surface simulation of heterogeneous suspensions

The complexity of the interactions between the constituent granular and liquid phases of a suspension requires an adequate treatment of the constituents themselves. A promising way for numerical simulations of such systems is given by hybrid computational frameworks. This is naturally done, when the Lagrangian description of particle dynamics of the granular phase finds a correspondence in the ...

Micromechanics of Undrained Response of Dilative Granular Media 1 Using a Coupled DEM - LBM Model : A Case of Biaxial Test

16 In this paper the Discrete Element Method (DEM) is coupled with the Lattice-Boltzmann 17 Method (LBM) to model the undrained condition of dense granular media that display significant 18 dilation under highly confined loading. DEM-only models are commonly used to simulate the 19 micromechanics of an undrained specimen by applying displacements at the domain boundaries 20 so that the specimen...

Using DEM in Particulate Flow Simulations

scour modeling piles of kambuzia industrial city bridge using hec-ras and artificial neural network

today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...

Fluid Properties Effects on Sand Production using Discrete Element Method

Oil production may be accompanied by Sand Production (SP) in the weak sandstone reservoirs. Fluid flow is an important factor in transporting the separated grains and completing the SP mechanism. In this paper, the effect of fluid parameters, fluid flow, and fluid pressure on the SP is investigated by applying the Discrete Element Method (DEM). Parametric studies show that fluid velocity is red...
