2D model of a grit chamber with and without deflector, velocity map
Challenge

Check the hydraulic performance of a tank and its outlet bell, and improve flow distribution in a grit chamber.

Solution

We simulated the tank at maximum and average levels with OpenFOAM. For the grit chamber we compared the current layout with a deflector channel that splits the flow more evenly between channels.

Tools

OpenFOAM (interFoam), 2D shallow-water model, ParaView.
