Abstract: | Laboratory experiments have shown that screens or porous baffles with a porosity of about 50-60% can be used as effective energy dissipators below small hydraulic structures, either in a single wall, a double wall with the different angles at 45º, 90º and 135º. The experiments were carried out for a range of unstable flow Froude numbers (F1) from about 1.5 to 6, and the relative energy dissipation is comparatively larger than that produced by the hydraulic jumps. The iron sheet screens or porous baffles creates free hydraulic jumps, imposed hydraulic jumps, and in some cases submerged jumps. The downstream flow was found to be supercritical flow and tail water depth after leaving the screen is equal to the .79 times to y2. |
