FLOW-3D is an accurate and robust free-surface CFD package, the ideal tool for modeling dam and spillway structures. Dam safety professionals and design engineers around the world rely on the efficiency and accuracy of FLOW-3D for quantifying all aspects of dam and spillway design, operation, and maintenance.
FLOW-3D makes it easy to generate rating curves and detailed velocity profiles for complex spillways, including the effects of air entrainment and transport. FLOW-3D also enables the quantification of structural stresses (pressure and shear forces) during normal and extreme operations, including transient effects due to gate operation. FLOW-3D is widely used to confirm the hydraulic performance of proposed spillway designs and to help professionals meet dam safety requirements.
How Manitoba Hydro Uses FLOW-3D to Design Spillways
Studies by Manitoba Hydro indicated that lateral contraction effects in the three-gated sluiceway at its Wuskwatim hydroelectric project in northern Manitoba could be substantially reduced if minor design changes were made. As a result, an approximate 5% increase in spillway capacity at the design head was realized. This allowed designers to raise the spillway invert and reduce overall construction costs.
