| Summary: | Experimental evaluation of the effects of relative size, curvature and location of
curved floor baffle blocks in the dissipation of energy and control of hydraulic
jump is presented. The flow over floor blocks with curved upstream edges (in
plan) was described by a set of dimensionless ratios using dimensional analysis
techniques. The solution was evaluated in the laboratory with respect to
measurable elements of the flow. The results have indicated that, for all flow
conditions, the curved blocks are generally more effective in lowering the
downstream kinetic energy than regular straight edges blocks; thereby, creating
optimum flow conditions having lower capacity for erosion of the downstream
channel bed together with economy in structural requirements. |
