The effects of MHD radiating and non-uniform heat source/sink with heating on the momentum and heat transfer of Eyring-Powell fluid over a stretching

Abstract

The analysis of heat dissipation over a layered stretching sheet under the control of magneto-hydrodynamic mixed convective flow of Eyring-Powell fluid is described in this study. The effect of heat emission and immersion is investigated. A viscous, incompressible, two-dimensional, and laminar fluid is assumed. The governing equations of momentum and temperature pictures are translated into a collection of non-linear differential equations using conformable similarity transformations. To obtain the mathematical solution of the governing equations, the shooting approach is modified. Fourth-order Runge-Kutta formulation is applied for the integration and Newton's formulation suffices to simplify initial guess values. MATLAB is used for all the programming. The effect of respective distinct flow parameters on the temperature, velocity, represented through graphical forms, and the interpretation of some helpful engineering aggregates such as the skin-friction coefficient and Nusselt number are explained graphically for different variables. It has been shown that increasing the thermal stratification parameter reduces fluid velocity and also temperature, and vice versa is noticed for the heat production variable.
