  • Title: Effect of secondary flows on Taylor-Aris dispersion.
    Author: Zhao H, Bau HH.
    Journal: Anal Chem; 2007 Oct 15; 79(20):7792-8. PubMed ID: 17880184.
    Abstract:
    We study theoretically the effects of secondary (transverse) flows on the Taylor-Aris dispersion of pressure-driven, open column flow in a conduit with a rectangular cross section and account for the interaction of solutes with the retentive coating on the conduit's surface. A few plausible means of inducing secondary flows (that are independent of the primary, pressure-driven, axial flow) are described. The Taylor-Aris dispersion coefficient is computed as a function of the secondary flow's pattern and intensity. By inducing secondary flows, one can significantly reduce dispersion.
