Entropy Generation for MHD Maxwell Nanofluid Flow Past a Porous and Stretching Surface with Dufour and Soret Effects

In this study, the entropy generation for magnetohydrodynamic (MHD) mixed convection and Maxwell nanofluid flow is discussed. The flow is considered over a stretching and penetrable surface. The thermal conductivity, velocity slip condition, and thermal radiation are also considered for the flow system. The entropy generation and irreversibility analysis have been considered and the impact of the physical parameters has been observed. The modeled equations are converted into a set of non-linear ODEs with the help of similar transformable variables. The sophisticated homotopy analysis method (HAM) is used to obtain analytic approximations for the resulting system of non-linear differential equations. Among the many outputs of the study, it is found that the velocity distribution is a decreasing function of Maxwell, magnetic parameters, and an increasing function of mixed convection factor within the boundary layer. Temperature profile upsurges with a consistent expansion in radiation thermophoretic and Dufour parameters. The Bejan number increases with an increase in the Brinkman number and radiation parameter. The concentration profile increases with an augmentation of the Soret number and decreases with increasing values of the Schmidt number.
