Analysis of entropy generation and nonlinear convection on unsteady flow of MHD Prandtl fluid with Soret and Dufour effects

Abstract Here the assessment of entropy generation with Soret and Dufour impact in flow MHD Prandtl fluid along an unsteady stretching surface has been measured. Nonlinear mixed convection convective conditions for heat/mass transfer are imposed at surface. The outcome viscous dissipation radiation is considered heat features. obtained system nonlinear PDEs converted to ODEs by consuming dimensionless variables. Resulting systems solved convergent solutions. Impacts parameters, unsteadiness parameter, numbers, magnetic thermal concentration number, Biot ratio buoyancy, Eckert number Schmidt addressed. Skin friction coefficient, local Nusselt Sherwood numbers analyzed graphically. Unsteady parameter $${ \epsilon }$$ ϵ reverse behavior on velocity temperature profiles, declines while raises. \alpha α \beta β boost field. Mixed le N * (ratio buoyancy force) enhance field resultant boundary layer thickness. Magnetic change its $$f(\eta )$$ f ( η ) $$\theta (\eta θ . Soret/Dufour enhances energy flux due mass rate which radically increases temperature. Far away from wall grows rapidly greater values a b. increase decreases.
