Abstract

Abstract: This research extends to investigate the effects of activation energy and thermal radiation on mixed convection striation point flow of Carreau liquid toward the stretchable sheet. Heat transport assessment is utilized in the existence of activation energy. For flowing formulations, Carreau substance rheological relationships are used. For modelling and simulation, the Buongiorno nanoliquid model with thermophoretic and Brownian diffusion features is used. The obtained partial differential equation is converted to an ordinary differential equation by utilizing appropriate transmission. The mathematical formulation of the outcoming equation is achieved by utilizing the RK-Fehlberg approach with the bvp4c technique. This assessment illustrates several significant empirical features of flow and heat transport. Numerical simulations are taken for various scales of Hartmann number, temperature ratio parameter, and Schmidt number. The assumption is that the velocity estimation reduces the Hartmann number. The opposite result of the thermal ratio parameter remains valid for the Nusselt effect and temperature curve. Furthermore, the influence of Schmidt quantity on the Sherwood amount and solutal contour are extremely opposite.
