About This Lesson
- The problem numerically simulates particle-laden airflow in a long pipe with a bend using ANSYS Fluent software.
- We perform this simulation in steady state for the fluid phase with unsteady (transient) particle tracking.
- We model the problem using a four-way coupled DEM–CFD DPM approach to capture particle–particle and particle–fluid interactions.
- The DEM collision model, Saffman lift force, and two-way turbulence coupling are included as per project requirements.
- The geometry is created in ANSYS Design Modeler and meshed in ANSYS Meshing with an unstructured grid of about 382,000 elements.
