Force on Sill of Forced Jump
The mean force on a continuous sill in a forced hydraulic jump has been measured directly by a transducer for a wide range of experimental conditions. Four sills of heights expressed as multiples of the sluice opening are 1.0, 1.5, 2.0, and 3.0. The Froude number based on the flow at the sluice opening is varied from 3.99 to 9.09. The sills are situated at various distances from the sluice gate. The state of the flow is governed by the depth downstream of the sill. Maximum force is exerted when the supercritical stream impinges directly on the sill. The force reaches an asymptotic value at high submergence and it could be predicted for high sills using an elementary dynamic pressure model. The scale effect due to Froude number of the flow is discussed.
