CFD velocity field in plan view of a circular tank at three depths

Challenge

Improve solids removal in existing circular tanks by changing the water inlet.

Solution

We compared several inlet manifold configurations with CFD, measuring the velocity field at different depths and particle removal efficiency, with and without fish, and recommended a configuration before any work on the tanks.

Tools

OpenFOAM, ParaView, Python.
