Abstract (EN):
The concentration distribution in the wake of a
soluble sphere immersed in a granular bed of inerts
has been obtained numerically, for transport by both
advection and diffusion/dispersion.
Fluid flow in the granular bed around the sphere was
assumed to follow Darcy¿s law and, at each point,
dispersion of solute was considered in both the crossstream
and streamwise directions. The elliptic PDE
equation, resulting from a differential material
balance on the solute, has been solved numerically
over a wide range of values of the relevant
parameters.
