| Summary: | <span>In present work a labyrinth (zigzag), in shape has been used to configure the steps of stepped <span>spillway by using the physical model. This configuration does not introduce previously by <span>investigators or in construction techniques of dams or cascades. It would be expected to improve <span>the flow over chute. A magnifying the width path of each step to become, L<span>T<span>, instead of, W, will <span>induce the interlocking between the mainstream and that spread laterally due to labyrinth path. This <span>phenomenon leads to reduce the jet velocities near the surfaces, thus minimizing the ability of <span>cavitation and with increasing a circulation regions the ability of air entrainment be maximized. The <span>results were encouraging, (e.g., the reverse performance has recorded for spillway slope). From the <span>evaluation of outcome, the average recorded of percentage profits of kinetic energy dissipation with <span>a labyrinth shape compared with the results of traditional shape were ranged between (13- 44%). <span>Different predictive formulas have been proposed based on iteration analysis, can be <span>recommended for evaluation and design.</span></span></span></span></span></span></span></span></span></span></span><br /><br /></span></span></span> |
