Measurements of single spherical particle trajectories with lateral migration in a slit with one porous wall under laminar flow conditions

High-flux membrane separation using fluid skimming dominated convective fluid flow

“…Inertial lift only takes place when the Reynolds number of the particle in a rectangular channel Re p (-) defined in Eq. (15) [14], is larger than 1, while the maximum Re p for the experimental conditions investigated is 3.5 × 10 −3 . Therefore inertial lift does not seem to play a role in the experiments.…”

“…Several studies have investigated hydrodynamics in combination with particle deposition for back-transport of particles away from the membrane (surface) [14][15][16][17][18][19], or on convective fluid behaviour above a well-defined membrane pore [20]. Feed suspensions with particles between 0.1 and 10 m have been studied and therefore shear-induced diffusion is the main back-transport mechanism.…”

Particle Trajectories in Field-Flow Fractionation and SPLITT Fractionation Channels

“…These assumptions were made by Belfort and coworkers (34)(35)(36)(37)63) and by Kleinstreuer and Chin (38). We assume that the channel walls are uniformly permeable and that the cross flow rate V, that enters one wall is withdrawn at the opposite wall.…”

Effect of electrostatic, hydrodynamic, and Brownian forces on particle trajectories and sieving in normal flow filtration

“…Belfort and colleagues [8][9][10] evaluated particle trajectories during cross-flow microfiltration by solving the NavierStokes equations, including the inertial terms to account for the presence of any inertial lift force. The membrane was treated as a uniformly porous boundary, without distinct pores.…”
