Flow Over Side Weirs in Circular Channels
暂无分享,去创建一个
Theoretical and experimental investigations of the flow over sharpedged side weirs in circular channels are reported. A theoretical model can be obtained from energy principles, and it is solved by a finite difference method. The results are presented in diagrammatic form for practical use. The experiments cover sub‐ and supercritical flow regimes, and water surfaces are observed for both. The discharge coefficients are obtained for sub‐ and supercritical regimes. Derived expressions for the side weir discharge and water surface profiles for these regimes are compared with experimental results.
