WebSep 29, 2015 · The concept of Taylor dispersion is extended to flow over patterned microchannel, where the presence of axial variation is incorporated. Fig. 2 illustrates the … Taylor dispersion or Taylor diffusion is an effect in fluid mechanics in which a shear flow can increase the effective diffusivity of a species. Essentially, the shear acts to smear out the concentration distribution in the direction of the flow, enhancing the rate at which it spreads in that direction. The effect is named … See more We use z as an axial coordinate and r as the radial coordinate, and assume axisymmetry. The pipe has radius a, and the fluid velocity is: The See more • Aris, R.
