Analysis of Trapezoidal Labyrinth Weirs Using Computation Fluid Dynamics (CFD)

Labyrinth spillways have higher discharge capacity than conventional spillways due to effective crest length enhancement. Several experimental studies have been conducted in recent years to investigate the hydraulic performances of labyrinth weirs. By using advanced numerical methods together with experimental studies, researchers can gain more knowledge about the behavior of such systems and obtain better designs. In this study, trapezoidal labyrinth weirs with four different side wall angles were analyzed under different hydraulic conditions by using the Computational Fluid Dynamics (CFD) method. In addition, the results obtained were compared with experimental data. Numerical simulation outputs have been examined and detailed results have been obtained about their designs
