dc.description.abstract In this article, we have investigated the Soret and Dofour effects on Casson nanofluid flowing in a vertical channel with the impact of thermal radiation. Entropy generation in the system is also analysed for the considered flow. Channel walls are assumed to satisfy the convective constraints of heat transfer. The governing equations are modelled using Buongiorno’s model by incorporating the effects of Brownian motion and thermophoresis. The equations are non-dimensionalised by defining suitable dimensionless parameters. The resulting equations are nonlinear and coupled. These are tackled by employing differential transform method and MATLAB bvp4c code based on finite difference method. Velocity, temperature and entropy generation are plotted for various physical parameters which affects the flow and are analysed graphically. Both the methods are observed to give the results with good agreement. Casson fluid parameter intensifies both velocity field and thermal field. Dufour parameter enhances both velocity and thermal field. Soret parameter also positively accelerates both velocity and temperature. Casson parameter, Dufour parameter, Soret parameter minimise the entropy generation in the system. en_US
