A review of shear-induced particle migration for enhanced filtration and fractionation
R.M. Klaver; C.G.P.H. Schroën Wageningen University, Wageningen, The Netherlands
Abstract
Insights into fluid dynamics and hydrodynamic particle interactions lead to new options for fractionation techniques aimed at separating particles between 1 and 10 μm in size. In microfiltration and flow field-flow fractionation these effects play a major role, but the interactions are complex and not fully understood. Computational models and experimental data from the literature both show that particle size segregation occurs. Enrichment of the larger particles in the centre of the channel takes place, but the extent to which this occurs is under debate. This ...
