Zusammenfassung: | Broad-crested weirs are
hydraulic structures installed in open-channels used to control the flow of
water and measure the discharge. In this study, the flow over a broad-crested
weir in open-channel was experimentally and numerically modeled. Experiments
were carried out in a channel with a length of 1.5 m and a width of 0.055 m
under five different flow rates. In each experiment, water depth and flow velocity
in flow direction were measured using a pitot tube. Numerical model was developed using SimFlow
software. The velocities and
pressure fields were computed numerically. The water depths and velocities in flow direction obtained from the
numerical model were compared to experimental values. There is generally a good
agreement between experimental and numerical results. Relatively small errors
in velocity profiles are observed in higher discharges. |
