Twin Screw Extruder CFD Simulation by ANSYS Fluent

Описание: In this project, a twin screw extruder is simulated using ANSYS Fluent to analyze the interaction of water and particles within the system.
The flow rate of particles is nine times that of the continuous phase, and both the interactions within the particle phase and with the continuous phase are considered using a 4-way DEM module.
The geometry is designed in ANSYS SpaceClaim, and an unstructured mesh is generated in ANSYS Meshing with dynamic adjustments at each time step.
The k-epsilon turbulence model and DPM model are employed along with the DEM module to simulate interactions.
This complex simulation, involving dynamic meshing and high computational demands, reveals insights into particle tracking and residence time as the extruder operates at 300 rpm with a 60-degree rotation scope.
