Soret and Dufour Effects on Radiative MHD Thermosolutal Viscoplastic Nanofluid Mixed Convective Flow Past a Bidirectional Stretching Sheet

Inspired by the ample applications of nanotechnology and nanoscience in science and engineering fields, a mathematical model is developed to study the boundary layer flow of magneto-hydrodynamic non-Newtonian (i.e., Casson fluid) nanofluid over a bidirectional stretching surface. The slip flow over the bidirectional surface is considered in addition to the Soret, thermal radiation, and Dufour effects. The suitable transformations are imposed on the partial differential governing equations and transformed into ordinary differential equations (ODEs), which are solved numerically by the bvp4c scheme. The flow mechanism due to the impacts of various governing parameters is exhibited through tabular and graphical forms. It is observed that for rising values of slip parameter, the velocity along x-axis is seen to diminish, but the trend is reversed along y-axis. The thermal boundary layer is thicker for the Dufour parameter. The current model may be useful in electric conductive nanomaterials that could be used in aviation, energy systems, and thermal augmentation of industrial flow patterns, among others. The MHD engine and generators, radiotherapy, soil mechanics, liquid metallurgy mechanism, thermal insulation, and many others are few important applications of such flows.
