Experimental and numerical modeling of various energy dissipater designs in chute channels

Abstract Energy dissipater in the stilling basin is a structure designed to protect downstream of spillway from erosion and scour by reducing flow energy dissipation pool. pool an important element hydraulic structures as transition between high-velocity sensitive tail water. The aim this study investigate ratios baffle blocks which constructed Type III with different geometric shapes using physical numerical modeling methods. In all types blocks, block heights widths are chosen equally, total lengths be 50% width. ratio 4 was determined 3 layouts single row, two rows without threshold structure, 12 designs 7 rates tested. addition, these experimental studies were tested FLOW-3D software program, results compared. As result study, it that T-shaped energy-dissipating had highest ratio, observed obtained similar each other range 5%.
