When a soluble substance is introduced into a fluid flowing slowly through a small-bore tube it spreads out under the combined action of molecular diffusion and the variation of velocity over the cross-section. It is shown analytically that the distribution of concentration produced in this way is centred on a point which moves with the mean speed of flow and is symmetrical about it in spite of the asymmetry of the flow. The dispersion along the tube is governed by a virtual coefficient of…

Diffusion and Mass Transport in Tubes
When soluble matter is introduced into a solvent flowing slowly through a capillary tube it is dispersed longitudinally by a process which involves both the variation in fluid velocity over the cross
Dispersion due to molecular diffusion and macroscopic mixing in flow through a network of capillaries
This paper is concerned with the dispersion of a material quantity in the steady flow of a viscous fluid through a random network of capillaries (which is a useful model of a porous medium), for the
The effects of curvature and buoyancy on the laminar dispersion of solute in a horizontal tube
When a solute is injected into a straight circular tube through which a solvent is in steady laminar flow it spreads out longitudinally under the combined effect of molecular diffusion and advection

: The method used in an earlier paper ( Aris 1956) to discuss the dispersion of a solute in a fluid flowing through a tube is applied here to the case in which the solute can also pass into another
On the theory of dispersion of a solute during laminar flow in tubes
The problem of the diffusion of a solute during laminar flow through a circular tube is solved. A new method of the approximate solution of the corresponding diffusion equation is used. The
The concentration distribution produced by shear dispersion of solute in Poiseuille flow
One of G. I. Taylor's most famous papers concerns the large-time behaviour of a cloud of soluble matter which has been injected into a solvent in laminar flow in a pipe. In the past thirty years, a

A solute is released from the surface of a sphere flowing freely in a cylindrical channel mimicking a modern drug delivery agent in a blood vessel. The solute then disperses by the combined action of
Unsteady solute dispersion in two-fluid flowing through narrow tubes: A temperature-dependent viscosity approach
Abstract The drug delivery or transportation of nutrients to our body involves the solute dispersion process through physiological systems and hence affected by the varying nature of viscosity, heat
The approach to normality of the concentration distribution of a solute in a solvent flowing along a straight pipe
Taylor (1953, 1954 a ) showed that, when a cloud of solute is injected into a pipe through which a solvent is flowing, it spreads out, so that the distribution of concentration C is eventually a
