The principle priority of this study is to inspect the performance of two dimensional chemically reacting non-Newtonian fluid bearing Soret, Dufour, thermal radiation, heat source and slip effects. The flow is prompted by a slendering surface with variable thickness. Casson and Williamson fluid models are incorporated in this discussion. Governing equations are evolved and converted into ordinary differential equations using similarity transformations. We adopted homotopy analysis method (HAM) to pick up the solutions. The graphical and tabular results for velocity, temperature, concentration, skin friction factor, local Nusselt number and Sherwood number are secured for both Casson and Williamson fluids. The correspondence between the acquired and previous results reveals that they are in good correlation. It is found that there is a significant increase in the thermal boundary layer thickness when the strength of the Dufour number is increased.

The aspire of this study is to analyse the magnetohydrodynamic (MHD) three dimensional flow of nanofluid induced by an exponentially stretching sheet in the presence of radiation and heat source. Casson fluid model is espoused in this discussion. The repercussion of porous matrix on the Casson nanofluid is also considered. Analysis is carried out when the surface shows convective condition. Brownian motion and thermophoresis effects are considered. Governing equations are evolved and converted into ordinary differential equations using similarity transformations. We adopted homotopy analysis method (HAM) to pick up the solutions. Impact of various parameters is displayed through graphs and tables and discussed in detail. Dual solutions are established by taking Casson and Newtonian fluids. A comparison is made and the correspondence between the acquired and previous results reveals that they are in good correlation.
