Abstract


This pagination specifies the characteristics of Carreau nano-fluid model embedded with hydro-magnetic (MHD) effects and the energy equation is extracted through Cattaneo-Christov approach. The process of heat generation and chemical reaction are also carried out whereas the fluid flow having infinite shear rate viscosity is induced by the stretching sheet. The mathematical form is developed in order to get the coupled partial differential equations and admissible similarity transforms are used to construct the set of ordinary differential equations and then sorted out numerically by applying Runge-Kutta Fehlberg method supported with shooting scheme. The graphs are plotted that portrays the impact of fluid velocity and temperature towards various engineering parameters which reveals that the fluid temperature increases when enlarging heat generation parameter. The validations for the numerical values of skin friction coefficient are delineated with the existing literature [33]. Also, the numerical findings for the local Nusselt number are offered.
