Forward osmosis: Novel desalination of produced water and fracturing flowback

Treatment and reuse of oil and gas (O&G) production wastewater in a cost-effective and environmentally sound manner is critical for sustainable industrial development and for meeting stringent regulations. High salinity, free and emulsified hydrocarbons, silts and clays released from producing formations, and process additives common in O&G drilling wastewater render many conventional treatment...

DEM-CFD modeling and simulation of granular systems

Size reduction process is widely used in the chemical and pharmaceutical industries. Jetmill is one of the most commonly used tool for such processes due to advantages they over other mills such as low contamination and narrow product size distribution. However the efficiency of the jet milling process is very low, furthermore the jet-milling process is sensitive to many parameters such as feed...

Parallel Open Source Cfd-dem for Resolved Particle-fluid Interaction

In the following paper we present a parallelized resolved method for the simulation of the dynamics of immersed bodies within fluids. The algorithm uses the so called Fictitious Domain Method (FDM) and combines the Lagrangian Discrete Element Method (DEM) for the tracking of the bodies and a Computational Fluid Dynamics (CFD) method for the calculation of the flow and pressure field of the flui...

Modeling slow deformation of polygonal particles using DEM

We introduce two improvements in the numerical scheme to simulate collision and slow shearing of irregular particles. First, we propose an alternative approach based on simple relations to compute the frictional contact forces. The approach improves efficiency and accuracy of the Discrete Element Method (DEM) when modeling the dynamics of the granular packing. We determine the proper upper limi...

Coupled fluid flow and geomechanical deformation modeling

Accurate prediction of reservoir production in structurally weak geologic areas requires both mechanical deformation and fluid flow modeling. Loose staggered-in-time coupling of two independent flow and mechanics simulators captures much of the complex physics at a substantially reduced cost. Two 3-D finite element simulators—Integrated Parallel Accurate Reservoir Simulator (IPARS) for flow and...
