Hydraulic Calculations of a Slotted Separator Using the SSIIM Program

Abstract

Analysis of the results of the hydraulic calculations of a slotted separator, allowed for changes in the separator design taking into account the reduction of flow turbulence, ensuring the continuity of water flow and sediments as well as optimal location of the slots. The separator is an important element of the installation for hydromechanical removal of sediments from the bottom of a water reservoir. Tests were carried out on the physical and mathematical model. Hydraulic calculations and numerical simulations were carried out using the SSIIM (Simulation of sediment movements in water intakes with multiblock option) program. The program enables three-dimensional analysis of flows and transport of sediments in rivers and canals by solving the Navier-Stokes equation and the turbulent model k-. A number of numerical experiments of the separator work were carried out for various design solutions regarding the geometry of the inlet and outlet channels and their connection with the chambers as well as slots system. The numerical simulations and conducted research on a physical model, allowed to develop an optimal solution.
