Özet
The increase in population causes the need for water to increase day by day. The fact that water resources are limited further emphasizes the effective use of water. For this purpose, level-flow control of water transmitted through open channels is very important. Broad-crested weir types are widely used in these controls carried out through weirs. This study used a newly designed broad-crested weir type that had not been used before. The model created in the laboratory environment was tested for Q=7.84 l/s and Q=14.86 l/s flow rates. The experiments measured water surface profile, flow depths, and velocity values. The same model was tested in the numerical environment under similar flow conditions. For this purpose, three-dimensional solutions were performed with Ansys-Fluent software. The Realizable k-? turbulence model, which has been tested for reliability in previous studies and is suitable for this type of broad- crested weir flows, was preferred. In the numerical solution, the VOF method was used for the water-air interface. Thus, the data belonging to the numerical model was verified using experimental data. In general, it was observed that there was an agreement between the experimental and numerical data in terms of water surface profile, flow depths and velocities. As a result of this study, it can be said that it allows different broad-crested weir designs to be tested with less cost before moving on to field applications.
