Effect of Corner Shape on Hydraulic Performance of One-Cycle Rectangular Labyrinth Weirs

Abstract: The hydraulic performance of rectangular labyrinth weirs has been investigated by many researchers, however, the effects of the corner shape on the hydraulic performance of rectangular labyrinth weirs have not been addressed in the current literature. Accordingly, this experimental study aims to explore the effect of the corner shape of on discharge efficiency of rectangular labyrinth weirs. Five flat-crested rectangular labyrinth weirs, with five different corner shapes, were made of High-Density Polyethylene… Show more

“…The consequences of headwater inflation may have been responsible for this. As the effective lengths of the labyrinth weirs, L C , increased, the effect of headwater inflation reduced; a longer weir produces less headwater inflation [2,5,15]. As a result, by increasing the effective length of rectangular labyrinth weirs and increasing the M values (L C /B ratios), the effects of headwater inflation of rectangular labyrinth weirs can be mitigated.…”

“…It is thought that upgrading the corner designs of rectangular labyrinth weirs will reduce or eliminate nappe interference and boost hydraulic efficiency. Although many researchers have looked at the hydraulic performance of rectangular labyrinth weirs [4,5,9,10,[12][13][14], the hydraulic performance of rectangular labyrinth weirs with different corner shapes has not been explored in the existing literature, except by Yousif and Karakouzian (2020) [15]. Yousif and Karakouzian (2020), in an attempt to improve the hydraulic performance of rectangular labyrinth weirs, so as to alleviate the adverse effects of nappe interference and headwater inflation, studied the effects of the corner shape on the flow properties over the labyrinth weirs.…”
