Dufour and viscous dissipation effects on MHD natural convective Jeffery fluid flow past an infinite inclined vertical porous plate

Purpose The purpose of this paper is to analyze the Dufour and Viscous dissipation effects on magnetohydrodynamics (MHD) natural convective Jeffery fluid flow past an infinite inclined vertical porous plate. Design/methodology/approach Using the non-dimensional variables, the flow governing equations along with corresponding initial and boundary conditions have been transformed into non-dimensional form. The governing partial differential equations are transformed into dimensionless form and solved using the finite element method for various physical parameters. This method is powerful and stable. It provides excellent convergence and flexibility in providing solutions. Findings The obtained numerical results for physical governing parameters on the velocity, temperature and concentration distributions are exemplified graphically and presented quantitatively. The results indicate that velocity increases with higher values of thermal and solutal Grashof numbers, Permeability, Eckert and Dufour numbers, while it decreases under the influence of magnetic and inclination parameters. Furthermore, temperature and concentration profiles are strongly influenced by thermal and mass diffusion effects and the trends in skin friction, Nusselt number and Sherwood number provide valuable insights for future experimental and engineering applications. Originality/value The problem is moderately original. The finite element solutions are reduced to known previous solutions in some limiting cases of the present investigation and are found to be in good agreement with published work.
