Abstract
A stilling basin is designed to dissipate the kinetic energy of the flow by a hydraulic jump. The main objective of the present study is to investigate the free hydraulic jump characteristics created in a rectangular stilling basin with a modified guide walls as a current deflector to control the hydraulic jump. A single-vent regulator is tested for different relative deflection angle of the guide walls under the same flow conditions. The characteristics of the jump formed without the guide walls are compared to those of the jump formulated under presence of the guide walls. Theoretical models for U.S Froude number and relative energy losses were derived. The dimensional analysis was employed to drive expressions correlating the different variables affecting the free hydraulic jump phenomena. The derived theoretical models results are in good agreement with the experimental results. Finally, this study yielded conclusions which can be recommended in the design procedure and practical applications.
