Title

Hydrodynamic Forces Analysis on Stilling Basin’, s Bed with Negative Step and Roughened Bed

Pages

  99-109

Abstract

 Introduction: In many types of hydraulic structures, a considerable portion of the kinetic energy of the flowing water must be dissipated to prevent erosion of the channel downstream from structure. Various methods of energy dissipation have been used to achieve tranquil flow conditions. One of the most effective means of accomplishing the required energy dissipation is a hydraulic jump. The hydraulic jump can assume several different forms depending on the geometry of the channel boundaries. Methods: A negative step with abrupt drop can change length of jump, sequent depths, hydrodynamic forces and other characteristics of the hydraulic jump. Also using Bed Roughness in Stilling Basins is an effective method to increase jump efficiency and decrease jump length. In the present study, combination of rough bed and negative step is used to check the effect of this combination on hydrodynamic forces in Stilling Basins. Findings: The results showed that the most critical area in terms of maximum hydrodynamic forces and cavitation in this type of Stilling Basins can be find in 10. 44
