C O M Rocky and Ansys Fluent coupling (DEM-CFD): A powerful tool for simulating granular-fluid systems The coupled DEM-CFD approach is a promising alternative for modeling granular-fluid systems, enlarging the range of coupled particle-fluid processes that can be managed with numerical simulations. Complex phenomena such as pneumatic conveying, slurry flow inside grinding mills, between particles and fluids can be simulated and analyzed with these powerful tools. Considering the industry necessities for both single phase and multiphase simulations, both 1-way and 2-way coupling between Rocky and Ansys Fluent are provided. The coupling of the terms of the Navier-Stokes equation of fluid- to-particle interactions, which by taking into account drag, lift, buoyancy, virtual mass, angular momentum and other forces, provide physically consistent and very trustworthy results. The work that Rocky DEM and Ansys accomplished also allows Ansys Fluent to work with Rocky in parallel CPU and GPU capabilities, which leads to very fast DEM-CFD simulation results. This parallel processing methodology also opens up the possibility of simulating large multiphase flow problems, with many millions of different sized and shaped particles—historically a weak spot with DEM technology. A plugin designed for Ansys Fluent makes the combined DEM-CFD setup task easy, less error prone, and guarantees consistency between both physics. Rocky-Ansys Fluent coupling is a powerful tool for designing and troubleshooting particulate processes using simulation technology, enabling engineers to analyze a large range of processes in many different industries including oil and gas (e.g. drilling), agroindustry (e.g. grain transportation and drying), pharmaceutics (e.g. transport), mining (e.g. mineral washing), and many others.
