Natural convective mass transfer coefficients from vertical cylinders of varying aspect ratio, embedded in saturated porous media, were measured using the limiting diffusion current technique. A copper ion reduction from an acidified cupric sulphate solution was used as the electrolyte. Randomly packed identical glass spheres of different size formed the porous media that were saturated with electrolyte solution The obtained data are correlated in terms of modified Sherwood number (Sh_L* ), modified Rayleigh number (RA_L* ), and Darcy numbers (Da_L). The correlation is expected to work in the range
6 × 10⁴ < Ra_L* < 6.1 × 10⁶ and 1.40 × 10⁻⁶ < Da_L < 1.02 × 10⁻³.
