| Abstract: | Soret and Dufour impacts for third-grade liquid flow are examined. MHD (magnetohydrodynamics), Joule heating, and thermal radiation are studied. Properties beyond constant thermophysical characteristics are discussed. Convective condition of mass and heat transfer is addressed. First-order chemical reaction with entropy generation is deliberated. Finite difference method is implemented. Analysis for involved variables about quantities of interest is organized. The findings show that velocity for material parameters of fluid has increasing trend. Suction variable yields to decay in velocity. Radiation and suction variables reveal enhancement in temperature whereas higher Dufour number lower thermal field. Higher thermal Biot number improved temperature. Higher magnetic field and radiation variables enhance entropy generation rate. Nusselt number against radiation has deceasing behavior whereas Sherwood number for reaction rate shows opposite trend.
