Analysis of unsteady MHD Eyring-Powell squeezing flow in stretching channel with considering thermal radiation and Joule heating effect using AGM

In this paper, has been investigated the heat and mass transfer in an unsteady two- dimensional squeezing flow of magnetohydromagnetic (MHD) radiative non-Newtonian Eyring-Powell fluid between two parallel infinite plates in the presence of heat generation/absorption, thermal radiation and Joule heating effect. The partial differential equations governing the flow problem converted to ordinary differential equations by using suitable similarity transformation. After that the Akbari- Ganji,s Method (AGM) has been used to solve differential equations governing this problem and during comparing happened between AGM and Runge-Kutta Fehlbrg method (RKF) it's observing AGM is a method with high accuracy for solving differential equations. The main goal of this paper is to investigate the effects of changes in the values of several parameters on the velocity and temperature and also on the local skin friction coefficient, local Nusselt and Sherwood numbers. The most important results of analyzes are Lorentz force generated by magnetic field parameter in the fluid flow field which reduces velocity and decrease in fluid temperature by increasing thermal radiation parameter

Nonlinear thermal radiation effect on magneto Casson nanofluid flow with Joule heating effect over an inclined porous stretching sheet

In this paper, mixed convection on MHD flow of casson nanofluid over a non-linearly permeable stretching sheet has been investigated and analyzed numerically. The effects of thermal radiation, chemical reaction, heat generation/absorption, viscous dissipation, suction and Joule heating are considered. The Brownian motion and thermophoresis phenomenon are used to model nanoparticles (Buongiorno's model). After converting PDEs governing the problem to ODEs, they have been solved by Runge-Kutta Fehlberg fourth-fifth order method. Obtained results of investigating the effects of different parameters changes on velocity, temperature, and concentration profiles are reported as diagrams. Fluid flow velocity reduction by increase in Hartman number (magnetic field parameter) is due to existence of Lorentz drag force against flow, flow velocity reduction due to increase in casson fluid parameter, increase in temperature profile due to increase in radiation parameter, and nanoparticle concentration profile reduction due to increase in chemical reaction parameter are some of valuable obtained results. Also, in final section of this paper effects of different parameters on skin friction coefficient, local Nusselt and Sherwood numbers are investigated that positive and ascending behavior for all three are reported.
