Abstract

A theoretical investigation is performed for studying the flow of heat transfer features of Sakiadis and Blasius flow of magnetohydrodynamic Carreau fluid with thermal radiation. We also considered the Cattaneo-Christov heat flux model to control the heat transfer phenomena. Numerical solutions are carried out Runge-Kutta based Shooting technique. The effects of various governing parameters on the flow quantities are demonstrated graphically. Also, calculated the friction factor coefficient and local Nusselt numbers for the various non-dimensional governing parameters such as radiation parameter, magnetic field parameter, power index parameter and thermal relaxation parameter. We found that the thermal relaxation and thermal radiation parameters are help to improve the rate of heat transfer.
