MHD Free Convection Flow of Viscoelastic Fluid Through a Vertical Porous Plate with Thermal Conductivity under Soret-Dufour Influence

A study of MHD heat and mass transfer of viscoelastic fluid past a porous plate with thermal conductivity under soret-dufour effect is investigated. The governing boundary-layer equations are formulated with appropriate boundary conditions. The Roseland diffusion approximation is used to analyze the radiative heat flux and it is appropriate for non-Scattering media. The governing boundary layer equations were simplified and non-dimensional equation. The dimensionless equations were discretized and then solved using the Crank-Nicolson’s method. The velocity, temperature and concentration distributions are derived and discussed numerically and in tabular forms. It is observed that velocity increases with the increase in Gr (Grashof number), Jeffery fluid parameter and magnetic field M parameter but it decreases with the increase in Fs and Da.
