Phenomenological description of horizontal flow filtration that calculates specific deposit profiles

What is it about?

To evade the assumption of uniform deposition of particles within a certain zone, differential mass balance expressions are introduced in the present work. The local filtration efficiency in the gravity and main flow directions is quantified through the directional modulating functions that become available from a network-type simulator. Results for the filter coefficient correction factors are presented for the case of horizontal flow and are compared with results from downward filtration.

Why is it important?

Despite the fact that a variety of empirical models have already been proposed in the past, an analytical expression for the prediction of the performance of the porous medium during filtration process is not yet broadly accepted. In the particular case of horizontal flow filtration, a non-uniform distribution of particle and cluster deposits along the main direction of flow (width of the horizontal filter) is obtained, which necessitates a three-dimensional phenomenological description.
