Numerical and scale analysis of Eyring-Powell nanofluid towards a magnetized stretched Riga surface with entropy generation and internal resistance

The aim of current investigation is to report the impact of convective boundary conditions, heat generation, viscous dissipation, porous medium and activation energy on Eyring-Powell nanofluid over Riga plate. We have used the Darcy-Forchheimer model to characterized the effects of porous medium. The Riga plate describes as an electromagnetics actuator that is made of permanent magnets and recurring behavior of electrodes pointed on plane of surface. Mathematical formulation is derived with viscous dissipation, heat generation and activation energy. The numerical code of shooting method is developed based on Range-Kutta Method of order four to get the fast convergence and accurate results. It is analyzed that the temperature field shows an increasing behavior by varying the values of Eckert number (Ec) radiation parameter (Rd). The Eckert number and modified Hartman number Q accelerate both velocity and temperature profiles, respectively. The nanoparticle concentration profile increases with Eckert number. The walls shear stress is increases and decreasing behavior for the values of modified Hartmann number and Eyring-powell parameter.
