Description

Flow-through curves (FTC) were obtained experimentally in 2 rectangular setting tank models consisting of an inlet slot and an outlet weir. The most important of the FTC characteristics were calculated and plotted on a diagram, which is called the hydraulic efficiency diagram (HED). Using the HED it was shown that the hydraulic efficiency of the tank improves by placing the inlet slot away from the mid-depth, either close to the surface or preferably close to the bottom. Hydraulic efficiency improves further by the use of inlet deflectors, whose position (distance and submersion) is not very critical provided that die deflectors are effective and divert the incoming jet towards the bottom. Some flow characteristics (length of recirculation areas) were measured and correlated to FTC characteristics. (EN)
