Electrochemical Ionic Mass Transfer Correlation in Fluid-Saturated Porous Layer
Cho ES
A new ionic mass transfer correlation is derived for the fluid-saturated, horizontal porous layer. Darcy-Forchheimer model is used to explain characteristics of fluid motion. Based on the microscales of turbulence a backbone mass transfer relation is derived as a function of the Darcy-Rayleigh number, RaD and the porous medium Schmidt number, Scp. For the Darcy’s limit of Scp>>RaD, the Sherwood number, Sh is a function of RaD only. However, for the region of high RaD, Sh can be related with RaDScp. Based on the present backbone equation and the electrochemical mass transfer experiments which are electro plating or electroless plating, the new ionic mass transfer correlation is suggested in the porous media.
