Abstract

Solute dispersion due to an instantaneously released source in steady, laminar, axisymmetric flows with an axial inflow and radial outflow is investigated analytically. Attention is given to large-time characteristics of dispersion, where the concentration reduces in proportion to e−2λτ, where λ is an eigenvalue that depends on the axial inflow and τ is the time measured in units of axial-diffusion times. Prospects of some other flows are also considered.
