Experimental and numerical study the effect of flow splitters on trapezoidal and triangular labyrinth weirs

Nonlinear weirs are among the major structures used in water transfer. Thus, these have been subject of various studies. This study investigates effect flow splitters on discharge performance trapezoidal and triangular labyrinth one cycle. delves into effects installed crest one-cycle using numerical methods (Flow-3D) physical models. In model, two, four, or six vanes were placed at regular intervals. The results showed that weir offered 4% higher efficiency than its counterpart had better weir. can improve by up to 11%, coefficient was found be 10.2% simulation model.
