Abstract
We study the steady laminar advective transport of a diffusive passive scalar
released at the base of narrow three-dimensional longitudinal open channels
with non-absorbing side walls and rectangular or truncated-wedge-shaped
cross-sections. The scalar field in the advective--diffusive boundary layer at
the base of the channels is fundamentally three-dimensional in the general
case, owing to a three-dimensional velocity field and differing boundary
conditions at the side walls. We utilise three-dimensional numerical
simulations and asymptotic analysis to understand how this inherent
three-dimensionality influences the advective-diffusive transport as described
by the normalised average flux, the Sherwood
