On Cattaneo-Christov heat flux analysis with magneto-hydrodynamic and heatgeneration effects in a Carreau nano-fluid over a stretching sheet

摘要

This pagination specifies the characteristics of Cattaneo-Christov heat diffusion model for the stagnation point flow of a Carreau nano-fluid.The momentum equation is manifested with magneto-hydrodynamic effect and the generalised Fourier’s law and Fick’s law are consideredto manipulate the heat and mass flux with heat generation and chemical reaction. The fluid flow having infinite shear rate viscosity iscaused by the stretched sheet. The admissible transformations are invoked to alter the flow narrating coupled partial differential systeminto the coupled ordinary differential system. Later on, these equations are sorted out numerically with the aid of Runge-Kutta Fehlbergmethod supported with shooting scheme. The graphs are plotted that portrays the impact of fluid velocity and temperature towards variousengineering parameters which reveals that the fluid temperature increases when enlarging heat generation parameter. The validations forthe numerical values of skin friction coefficient are delineated with the existing literature. Also, the numerical findings for the local Nusseltnumber are offered.
