Non-Darcy Mixed Convection in a Doubly Stratified Porous Medium with Soret-Dufour Effects

Abstract EN

This paper presents the nonsimilarity solutions for mixed convection heat and mass transfer along a semi-infinite vertical plate embedded in a doubly stratified fluid saturated porous medium in the presence of Soret and Dufour effects.

The flow in the porous medium is described by employing the Darcy-Forchheimer based model.

The nonlinear governing equations and their associated boundary conditions are initially cast into dimensionless forms and then solved numerically.

The influence of pertinent parameters on dimensionless velocity, temperature, concentration, heat, and mass transfer in terms of the local Nusselt and Sherwood numbers is discussed and presented graphically.
