Review article

The article is devoted to the development of models of groundwater infiltration processes into sewer pipelines using the ANSYS CFX program. Using the finite element method, the program allows implementing a simulation of the filtration process through a slit hole in the pipeline wall. Various cases of the location of the hole and the inflow of groundwater to it are regarded, as well as possible options for setting the porous domain. The models obtained make it possible to visualize the process of groundwater inflow, evaluate quantitative indicators of the inflow of infiltration waters into drainage systems, and assess the speeds and flow rates of the infiltered liquid.
