Скачать или смотреть Sand Settlement in U-Bend Pipe | Eulerian Multiphase Simulation | ANSYS Fluent CFD

In this video, we simulate sand–water slurry flow in a U-bend pipe using the Eulerian–Eulerian multiphase model in ANSYS Fluent. The U-bend geometry creates strong curvature effects, leading to sand settling, particle separation, and secondary flow development. This CFD animation shows how sand accumulates at the bottom of the bend, how velocity changes affect particle movement, and how turbulence influences re-suspension.

🔍 What’s Inside This Video

Sand–water slurry flow behaviour
Eulerian multiphase modelling approach
Particle settlement and stratification
Secondary flow/Dean vortex effects
Pressure and velocity variations inside the bend
Clear visualization of sand concentration build-up

💡 Why This Simulation is Important

Sand settlement in bends is a major issue in slurry transport pipelines used in:

Mining & mineral processing
Oil & gas drilling
Dredging systems
Wastewater and chemical industries

This video helps understand how particle settlement occurs and how CFD can predict blockages, erosion zones, and pressure losses.
