Monte Carlo network simulation of horizontal, upflow and downflow depth filtration

Simulation of the dynamics of depth filtration of non‐Brownian particles

“…The initial filter coefficient, , decreases 0 as increases, in accord with the corresponding predictions s Ž of previous work see, for instance, Tien and Payatakes, 1979;. Tien, 1989;Burganos et al, 1992aBurganos et al, , 1995 . Region 1 shrinks, region 2 shifts left, that is, to lower r⑀ values, while main-0 taining its breadth, and region 3 expands to the left.…”

Hierarchical simulator of biofilm growth and dynamics in granular porous materials

“…Simulations of the depth filtration of non-Brownian particles (size larger than 2 lm) by Burganos et al [9][10][11] have shown that the fraction of convected-out particles is highly dependent on the detailed pore geometry and the superficial fluid velocity. In particular, the fraction of convected-out particles increases as the superficial velocity and/or the size of the constriction between neighboring grains increase.…”

A mathematical model of aluminum depth filtration with ceramic foam filters: Part I. Validation for short-term filtration

“…It is useful to stress that most of the reports requires that the center of a particle reaches the wall to be trapped. For our case, a criterion for trapping of the particles consider that the particle velocity at the inlet of the unit cell, u p , is equal to the local velocity of the fluid, [7] however, as was established in a user accessible subroutine, which indicated that a particle became attached to the wall when the pointed out by Burganos et al, [22] a more realistic value is obtained by considering that the particle velocity, at the inlet distance from its center to the wall was less than or equal to its radius, R. of the unit cell, is equal to the sum of the local fluid velocity, …”
