An Axisymmetric Problem of Suspension Filtering with Formation of Elastic–Plastic Cake Layer

The paper considers an axisymmetric problem of filtering suspensions with the formation a cake on filter surface. It is supposed that has elastic–plastic properties. Using mass conservation equation and Darcy’s law, suspension filtration equations at regime are derived, which characterize partial irreversibility characteristics when system unloaded after loading. An also derived describes increase in thickness cake. Problems for posed numerically solved. role deformation estimated. Distributions compression pressure, concentration solid particles cake, relative permeability mode primary secondary loading system, as well unloading first obtained. growth dynamics established. parameters plasticity terms particle mainly affect corresponding indicators, i.e., distribution shown, depending change model characterizing properties significantly. This indicates significant effect characteristics.
