In this paper, the free convection flow phenomenon on magnetized second-grade nanofluid over a nonlinear elongating surface has been modeled under assumptions of generalized Fick’s and Cattaneo–Christov heat flux relations. The non-uniform source sink thermal radiation effects are used in energy equation with Buongiorno model. effect activation chemical processes is also examined, making current numerical scrutinization innovative. mathematical model begins partial derivative equations...
