Joint effects of thermal diffusion and diffusion thermo on MHD three dimensional nanofluid flow towards a stretching sheet

“…The effects of thermophoresis, Soret, and Dufour on the heat and mass transfer flow of a magnetohydrodynamics non-Newtonian nanofluid over an inclined plate were examined by Idowu and Falodun [3]. In order to investigate the combined effects of Soret, Dufour, and radiation of a viscoelastic fluid over an exponentially growing surface, Kasali et al [4] employed the Cattaneo-Christov heat flux model. In an inclined rectangular enclosure with a partly saturated porous wall, Hu and Mei [5] studied the combined effects of heat and moisture convection and entropy production in the presence of Soret and Dufour numbers.…”
