Using Computational Fluid Dynamics For Predicting Hydraulic Performance Of Arced Labyrinth Weirs, Shelby J. Koldewyn

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Our world is dynamic and as hydrologic research continues, the magnitude of flood estimates used in hydraulic design for reservoirs has increased. Consequently, many existing spillways are now undersized and unable to meet discharge requirements. These spillways often have a fixed footprint, so nonlinear weirs (e.g., labyrinth weirs) are often a viable solution. For reservoir applications, arcing labyrinth weirs in plan view increases hydraulic efficiency because of better cycle orientation to the approaching flow from the reservoir. This study supplements available physical arced labyrinth weir hydraulic data by observing flow characteristics of two numerical models (α=16°; θ=10° …
