Abstract

The characteristics of double-diffusive convection are investigated in an initially quiescent, thermally stratified horizontal porous layer. By considering Soret effects, a new predictive model for the ionic mass transport correlation is developed in a Darcy-extended porous layer by extending the micro-turbulence model. These theoretical results are compared with the experimental results of ionic mass transfer in an electrolyte-saturated porous layer with both electrostatic fields and temperature stratification. It is observed that the present correlation of the Sherwood number represents the experimental results very well.
