Solving the World’s Toughest CFD Problems

Water Treatment

Water and wastewater recovery facilities offer a unique set of modeling challenges. Moving water through a treatment plant includes a mix of flow diversions, flow splitting, free surface and pressurized pipe flow conditions, with head loss and detailed velocity fields all important modeling outcomes. Other process modeling challenges include aeration, hindered settling, chemistry, and impeller motion. FLOW-3D HYDRO‘s advanced auxiliary models allow modelers to go beyond the hydraulics of the flow. Grit removal, chlorine contact tanks, sludge settling and aeration all have their own dedicated models and give the user full flexibility into choosing the level of sophistication of their modeling effort. With its TruVOF capabilities, FLOW-3D HYDRO can seamlessly handle a range of free surface pressurized flow conditions.

Description

Sanitary Sewer Overflow (SSO) events have negative effects on human health and the environment. Flap gates can be used as constriction flow meters for the estimation of SSO discharge. FLOW-3D HYDRO provides powerful insights into the analysis of fluid-solid interaction. This can be used for direct estimation of flow rate at a specified head differential and flap gate diameter. Additionally, factors like density variations of flap gate cover, the thickness of flap gate cover, angle of flap gate at the opening, hinge point locations, etc. can be considered and tested in FLOW-3D HYDRO. The simulation model is validated by comparing the results with that of the experimental. A good agreement between the results of the FLOW-3D HYDRO model and experimental results can be seen.
