Computer modeling of flow on the object of the sewer network

Abstract

This work deals with the creation of a hydrodynamic model of the combined sewerage overflow chamber in Banská Bystrica. As an object on the sewer network, we chose a combined sewerage overflow chamber, because its correct functionality directly affects the quality of the environment in the recipient. Simulations were calculated in the program Ansys Workbench 19.2 – Fluid Flow (Fluent). The basis of the work was the creation of a 3D graphic model. The 3D model serves as a base for flow modeling. The core of the work are simulations in the combined sewerage overflow chamber that should correspond to real flow. The goal of our work is to compare the influence of inflow velocity and flow rakes on hydrodynamic flow.
