Abstract

Electroosmotic flows in axisymmetric capillaries with random zeta potentials were shown in [1] to exhibit axial velocity fluctuations about the mean plug flow. In this note we address the calculation of Taylor dispersion in such flows, and highlight the important differences between cross-sectional averaging (as usually used for dispersion problems) and ensemble averaging (as used in [1]).
