Modeling flows in permeable pressure systems and channels

The study is focused on the velocity and pressure distributions in flows in pipeline systems, as well as hydrological parameters of open flow examined on the basis of Saint Venant equations with allowance made for lateral inflow and the equations of motion of incompressible fluid in perforated or porous pipes. Some analytical solutions are given for the formulated boundary problems, which can be applied to the calculation of operation regimes of sprinkling machines of the “Fregat” or “Valey” type.
