| Abstrait: | The labyrinth spillways are utilized to cater a more discharge capacity than straight overflow spillways. The capacity of a labyrinth spillway has dependents on total head, effective crest length, and discharge coefficient. The labyrinth spillway is utilizing as an overflow structure in large reservoirs. In the present study, guide vanes were utilized to increment the discharge coefficient of triangular labyrinth spillway. The different configurations of guide vanes on the upstream face of the spillway in a rectangular horizontal channel were examined. These different configurations were repeated for 3 widths of guide vanes. Experiments were operated for sub-critical, stable and free overflow conditions. Finally, the results show that the discharge coefficient of the triangular labyrinth spillway putting guide vanes had higher values than that of simple triangular labyrinth spillway. Putting 4 guide vanes in the first-quarter and fourth-quarter of two side legs can increment the discharge coefficient up to 18 %. |
