Methodological Proposal for the Hydraulic Design of Labyrinth Weirs

A labyrinth weir allows for higher discharge capacity than conventional linear weirs, especially at low hydraulic heads. In fact, this is an alternative the design or rehabilitation of spillways. It can even be used as a strategy in problems related to dam safety. sequential method based on optimal geometric parameters and results flow analysis using Computational Fluid Dynamics experimental studies reported literature. The tests performed were weirs with values HT/P ≤ 0.8 angles cycle sidewall 6° α 20°. coefficient are presented family curves, which indicates when 0.17. Four aeration conditions identified nappe adhering downstream face wall lower drowned. Unstable was present 12° 20°, greater presence partially aerated interference characterized quantified, reaching up 60% length between apex, curves function respect. Finally, spreadsheet flowchart proposed support type weir.
