two-way coupling - Opis:
- The computational fluid dynamics coupled with the discrete element method is widely employed to simulate particle-fluid interactions in solid-liquid flows. The restrictions imposed by the CFD-DEM scheme to very fine meshes contribute to a scant amount of numerical results of particle settling in viscoplastic fluids. This paper presents the two-way coupling CFD-DEM simulation of the particle sedimentation in a quiescent Bingham fluid. The results for terminal particle velocity showed good agreement with the experimental data. Owing to the viscoplastic behavior of the fluid, low values of the relaxation parameter of the solid-phase must be specified to obtain accurate results.
