Abstract

Natural convective mass transfer from upward-pointing vertical cones, embedded in saturated porous media, has been studied using the limiting diffusion current technique (LDCT). The measured mass transfer coefficients are correlated by Sh_l = 1.4074 (Ra*_l/Da_l)^0.3035, where Sh*_l and Da _l are modified Sherwood number, modified Rayleigh number, and Darcy number, respectively. The correlation is expected to predict well in the range of from Ra*_l from 7.8 × 10⁴ to 7.6 × 10⁶ and in the range of Da_l from 1.09 × 10^-6 to 6.05 × 10^-4.
