Fundamental Areas / Numerical Analysis of Partial Differential Equations
These figures illustrate the fill-up of a secondary clarifier that is part of a wastewater treatment plant. The first figure presents the axisymmetric domain, along with its dimensions and different parts of its boundary. The second and third figures present snapshots of the concentration, the pressure, and radial and vertical velocity components at several instants. The numerical method employed is a new finite volume element discretization. More details can be found in :
