What is Performance Evaluation of Impact Stilling Basin Using ANSYS Fluent about?

Impact stilling basin or USBR type VI basin is a unique energy dissipator device that is installed at downstream of culverts, detention basin, and pipe outlets to prevent erosion and scouring. Its box-type structure with hanging baffle dissipates the energy of flowing water through impact thereby creating vertical eddies and consequently reducing the velocity of flow. In this study, a 3D model of impact basin is developed using ANSYS workbench, and its performance is analyzed in different scenarios using ANSYS Fluent R15.0 software. These different scenarios are taken as per those in published experimental work. Simulations are run for these cases in ANSYS Fluent by varying the position of baffle wall from both basin inlet and basin floor. Values of parameters such as turbulent kinetic energy, velocity of flow, wall shear stress and energy losses (kinetic energy and specific energy) are computed at the basin outlet for different cases to determine the position of baffle wall for maximum energy dissipation. Results from simulations show that maximum dissipation of energy occurs when the wall is placed at a distance of 4d from inlet with a gap of 1d from the floor, where 'd" is taken
