Experiment and Numerical Simulation of Rotating Speed of Blade in Sandstone Wastewater of Rotational Flow Grit Chamber

Abstract:

The high-turbidity solid-liquid two-phase problem of the complex flow pattern is of greatest importance for the grit chamber with rotational flow. An Eulerian-Eulerian two-phase model for describing the collision force between particles in sandstone wastewater properly was developed. A bench scale experiment combining with a hydroelectric project was conducted. By analyzing the removal efficiency at different speeds of blade, the optimized rotating speed was obtained. Based on the optimized rotating speed, three-dimensional numerical simulation of the two-phase flow field was studied. The simulation results showed that when the number of blade is four, the optimum removal efficiency can be reached, which was found to be in reasonable agreement with the experimental data.
