FLOW-3D is used in the water and wastewater industry to design and analyze municipal applications such as:
- Mixing, settling, and contact tanks
- Control structures like weirs, gates, ramps, and orifices
- Combined sewer (CSO) and stormwater sewer (SSO) overflow facilities
- Pump and lift stations
- Treatment plant headworks
- Filtration systems and passive earth and stone filters
- Baffle and wall placement
- Hydraulic efficiency and short-circuiting
FLOW-3D is optimized for modeling both free-surface and constrained flow patterns and seamlessly models situations that switch between free-surface, pressurized, sub-critical, and super-critical flow conditions. Additional physics packages are included with FLOW-3D to model the most complex situations, including:
- Flow bulking due to air entrainment
- Air bubble escape and air pocket pressurization
- Drifting and settling particulate matter and the effect on the flow pattern of sediment accumulation
- Chemical reactions
- Moving gates and paddles
- Fast-spinning bladed objects, pumps, and impellers
- Dissolving and eroding solids
- Granular flow (slurries)
