Abstract

The objective of the present study was to make a theoretical study based on a CFD analysis for a conventional radial clarifier. The parameters of the Computational Fluid Dynamics analysis were set in the Ansys software, and after running the simulation, the values for fluid velocity, turbulence intensity and Reynolds number were obtained. Thus, it was obtained a fluid velocity of 0.103 m/s, a turbulence intensity of 3.82·10-2 % and a Reynolds number of 147. This work can help researchers in the field, mainly, but also radial clarifier manufacturers to optimise the process.
